This is a suit in equity brought by plaintiff taxpayers against School District No. 62C, its board and clerk, to enjoin defendants from supplying textbooks without charge for the use of pupils enrolled in St. John’s The Apostle School, a parochial school maintained and operated by the Catholic church. Plaintiffs also ¡seek a judicial declaration that the so-called free textbook statute (ORS 337.150), under Which distribution was made to the 'St. John’s school and other parochial schools, does not authorize defendants to supply textbooks free of charge to church or parochial schools, or if the statute is so construed that it be declared rmconstitutional.
Ivan B. Carlson, a resident within School District No. 62C, whose children were enrolled in the St. John’s school intervened.
The statute in question, ORS 337.150, reads as follows:
“337.150 (1) Each district school board shall, in the manner specified in ORS 328.520 and 328.525, provide textbooks, prescribed or authorized by law, for the free and equal use of all pupils residing in its district and enrolled in and actually attending standard elementary schools or grades seven or eight of standard secondary schools.
“(2) For the purpose of ORS 328.520, 328.525 and 337.150 to 337.250 a school shall be standard when it meets the 'standards of the State Board of Education, except with respect to those standards applying to the ratio of pupils to the acre of school site, the square feet of classroom floor space per *241pupil and the ratio of pupils to teachers in classrooms, and when 'ah teachers engaged in classroom instruction in said school hold a valid Oregon teaching certificate of the proper teaching level. The holding of such a teacher’s certificate shall be evidenced by annual registration with the county school superintendent of the county in which the school is situated.”
Plaintiffs attack the constitutionality of the statute on four grounds; (1) it authorizes state aid to religion at public expense in violation of the First Amendment to the United States Constitution as made applicable to the states by the Fourteenth;① (2) the furnishing of such textbooks constitutes a benefit to religious institutions contrary to the provisions of Article I, §5 of the Oregon Constitution;② (3) it, in effect, imposes a tax f or a non-public purpose and thus deprives plaintiffs of property without due process of law, and (4) it authorizes the expenditure of money not exclusively for the support and maintenance of the common schools and is, therefore, in violation of Article VIII, § 2 of the Oregon Constitution.③
*242Plaintiffs rely principally upon the first two grounds in attacking the constitutionality of the statute. The trial court held OPS 337.150 constitutional. Plaintiffs appeal.
For a period of several years the defendant district has furnished free textbooks for the use of the pupils of St. John’s school. In a period of three school years these books have cost the district approximately $4,000. The books were purchased by the ¡district from money in its General Fund, a part of which was derived from taxes levied upon real property in the district, including real property owned by plaintiffs. Books furnished by the ¡district under OPS 337.150, whether to public or to parochial schools, are delivered to the persons in charge of the schools—not to the pupils individually. The district also furnishes teacher’s editions of each text. The district retains title to the books, a matter of little practical significance however, because the books are not ordinarily retrieved by the district. Textbooks furnished for 'the use of parochial school students do not differ from those delivered to public schools. A school is not entitled to receive free text*243books unless it complies with standards established by the Oregon statutes as implemented by administrative regulation. The St. John’s school met these standards.
The evidence establishes, and the trial judge found, that the purpose of the Catholic church in operating the St. John’s school and other similar schools under its supervision is to permeate the entire educational process with the precepts of the Catholic religion. The study guides used by the teachers in St. John’s school indicate that, to some extent at least, 'the use of the textbooks furnished by the district is inextricably connected with the teaching of religious concepts. These study guides were prepared by the superintendent of schools of the Archdiocese of Portland. There is no doubt that the teaching of the subject matter in this manner in a public school would be contrary to law.④
Defendants first challenge plaintiffs standing to raise any constitutional issue other than the violation of the due process clause of the Fourteenth Amendment. Plaintiffs have not shown, it is argued, a deprivation of any freedom guaranteed by the First Amendment since they do not sue as school children, parents of school children, or as persons whose own religious liberty is threatened. As will appear below, we have chosen to decide the issues presented in this case solely upon the basis of the Oregon Constitution. It is not necessary, therefore, to decide whether under federal law defendants’ contention with respect to standing is sound.⑤
*244The question of plaintiffs’ standing to assert Article I, § 5 in this cause is not directly raised by defendants. The Oregon cases on standing do not provide us with a clear guide. It has been held that for some purposes at least a person contesting a public expenditure must plead and prove that the threatened action probably will result in a general increase in taxation.⑥ Plaintiffs did not expressly allege in their complaint that the expenditures made by the defendant district increase the tax burden upon them or upon taxpayers generally, although the claim that such an increase occurs might be .inferred from the allegations that plaintiffs are taxpayers, that public moneys were appropriated and expended in the purchase of textbooks for distribution to St. John’s school and that this “constitutes the imposition of a tax.”⑦ The precise question of whether a taxpayer has standing to contest the expenditure of public moneys for the support of religious education has been passed upon by other courts. In some of the adjudicated cases the taxpayer has been accorded standing even in the absence of allegation or proof that he will be damaged in a pecuniary way.⑧ And there is support for the proposi*245tion that 'the problem of standing will be overlooked when an issue of unusual importance is presented.⑨
In the instant case the issue of plaintiffs’ standing was not raised by defendants’ pleadings. If standing were a jurisdictional matter then, of course, defendants could raise the question at any stage in the proceedings. But we do not so regard it and we hold, therefore, that defendants’ failure to raise the issue by a proper pleading constitutes a waiver of that issue.⑩
The First Amendment, as interpreted in Everson v. Board of Education, 330 US 1, 67 S Ct 504, 91 L Ed 711, 168 ALR 1392 (1946) and Article I, § 5 of the Oregon Constitution prohibit the use of state funds for the benefit of religious institutions. The principal issue presented to us is whether the expenditure of public funds by the defendant school district for the purpose of furnishing textbooks free of charge to pupils of a parochial school is within these constitutional prohibitions.
We have concluded that the expenditure authorized by OBS 337.150 is within the proscription of *246Article I, § 5 of the Oregon Constitution. It is unnecessary, therefore, to consider plaintiffs’ contention that the statute violates also the First or Fourteenth Amendments to the United States Constitution. Nor is it necessary to consider whether Article "VIII, § 2 of the Oregon Constitution has been violated.
Article I, § 5 prohibiting the use of public moneys “for the benefit of any religious or theological institution,” was designed to keep separate the functions of state and church and to prevent the influence of one upon the other. In this respect our constitution follows the general pattern of other state constitutions and may be regarded as expressing, in more specific terms, the policy of the First Amendment as it has been explained in the Everson case.⑪
The historical setting in which constitutional provisions such as Article I, § 5 were written and the factors which prompted their adoption have been thoroughly explained elsewhere; it is not necessary, therefore, to restate those observations here.⑫ We need only say that we regard the separation of church and state no less important today than it was at the time Article I, § 5 and its counterpart in other constitutions were adopted.⑬
*247The general policy is clear. Our problem is to determine whether that policy is violated by the distribution of free textbooks to parochial schools under ORS 337.150. A simple solution would be to declare that Article I, § 5 prohibits the legislature from conferring any benefit upon religious institutions including church supported schools, no matter how indirect it might be. But the principle of separation of church and state has not been applied in such strict form. A certain amount of interplay of influences exercised by state and church has been permitted. It is not difficult to cite examples. Thus, we find that provision is made for chaplains in both houses of Congress and in the Armed Forces; for chapel services at West Point and Annapolis; sessions of the legislature are opened with prayer; the Bible is used to administer oaths, and many other religious practices and connotations are found in the functioning of government, both state and federal.⑭
Moreover, the wall of separation has not been re*248garded as a barrier preventing all financial aid to religious institutions. In some instances the aid is direct and substantial.⑮ In others 'the financial aid flows indirectly and incidentally as a result of a tax exemption or other favored treatment,⑯ or through an expenditure for a governmental purpose clearly within constitutional limits.⑰
For the most part these cases afford us little assistance in the interpretation of our own constitution. This is so because in some of them the controlling constitutional provision differs from ours or is seen against a different historical background. In many instances it is obvious that constitutional principles have been sacrificed to serve urgent needs of the *249community and state;⑱ and in others there simply has not been any real analysis of the problem.⑲ Some of these cases are strongly relied upon by defendants. We do not propose to appraise each of the numerous eases which have attempted to draw the line of distinction between expenditures which are within and expenditures which are outside constitutional limits.⑳ The reasoning employed in these oases will be examined as we consider defendants’ argument.
Defendants’ principal argument in support of the statute is that the expenditure of public funds for the purpose of furnishing books to pupils of parochial and public schools benefits the pupils who receive these books and not the schools themselves. The leading case for this proposition is Borden v. Louisiana State Board of Education, 168 La 1005, 123 So 655, 67 ALR 1183 (1929). In that case a statute similar to ORS 337.150 was attacked on constitutional grounds essentially the same as those asserted in the case at bar. The Louisiana court, with three Justices dissenting, sustained the statute on the ground, among others, *250that the expenditure was for the benefit of pupils and not in aid of schools.㉑
This so-called “child benefit theory” has been applied in other cases in which the expenditure of public funds is made for the purpose of meeting the educational needs of pupils, including those attending parochial schools.㉒ The difficulty with this theory is, however, that unless it is qualified in some way it can be used to justify the expenditure of public funds for every educational purpose, because all educational aids are of benefit to the pupil. This criticism is made in Gurney v. Ferguson, 190 Okla 254, 255, 122 P2d 1002, 1003-1004 (1942). In passing upon expenditures for the transportation of children attending parochial schools the court said:
“* * * It is true this use of public money and property aids the child, but it is no less true that practically every proper expenditure for school purposes aids the child. We are convinced that this expenditure, in its broad and true sense, and as commonly understood, is an expenditure in further*251anee of the constitutional duty or function of maintaining schools as organizations or institutions. The state has no authority to maintain a sectarian school. Surely the expenditure of public funds for the erection of school buildings, the purchasing and equipping and the upkeep of same; the payment of teachers, and for other proper related purposes is expenditure made for schools as such. Yet the same argument is equally applicable to those expenditures as to the present one.”
And, as observed by the same court, if the expenditure is not in aid of schools the use of school funds would be unauthorized and illegal.㉓
The leading case rejecting the child benefit theory is Judd v. Board of Education, 278 NY 200, 15 NE2d 576, 118 ALR 789 (1938). In that case the validity of a statute authorizing, the expenditure of public funds for the transportation of pupils to and from parochial and private school's was in question. The court said:
“* * * Free transportation of pupils induces attendance at the school. The purpose of the transportation is to promote the interests of the privatschool or religious or sectarian 'institution that controls and directs it. ‘It help's build up, strengthen and make successful the schools as organizations’ (State ex rel. Traub v. Brown, 36 Del. 181, 187, writ of error dismissed, Feb. 15, 1938). Without pupils there could be no school. It is illogical to say that the furnishing of transportation is not an aid to the institution while the employment of *252teachers and -furnishing of books, accommodations and other facilities are such an aid.” Id. at 212, 15 NE2d at 582.
The furnishing of textbooks even more clearly constitutes an educational aid. In the Everson case the expenditure for -the transportation of parochial school pupils was upheld on the theory that the state could provide for the protection of all school children from, traffic hazards irrespective of the -religious or public character of schools which they attended. Assuming that the court’s reasoning in Everson is sound, it is not applicable -to the case at bar. The expenditure of public funds for textbooks supplied to pupils of parochial schools is clearly identified with -the educational process, and does not warrant the assumption made in the Everson case that the expenditure is for the general welfare thus justifying. the use of the state’s police power.
The most recent appraisal of the child benefit theory which has. been brought to our attention is Matthews v. Quinton, (Alaska) 362 P2d 932 (1961). In that ease a statute authorizing the transportation of children attending non-public schools was held to be in violation of the Alaska constitutional provision prohibiting -the appropriation of public money for the support or -benefit of any sectarian, denominational or -private school. After a careful examination -of the cases in which the child benefit theory had been considered, the court rejected the theory, holding that the furnishing of transportation to pupils of non-public schools constituted a direct benefit to those schools. Mr. Justice Rutledge’s 'dissent in the Everson case was relied upon to support this conclusion. There it was -said:
“Finally, transportation, where it is needed, is *253as essential to education as any other element. Its cost is as much >a part of the total expense, except at times in amount, as the cost of textbooks, of school lunches, of athletic equipment, of writing and other materials; indeed of all other items composing the total burden. Now as always the core of the educational process is the teacher-pupil relationship. Without this the richest equipment and facilities would go for naught. See Judd v. Board of Education, 278 NY 200, 212, 15 NE2d 576, 582. But the proverbial Mark Hopkins conception no longer suffices for the country’s requirements. Without buddings, without equipment, without library, textbooks and other materials, and without transportation to bring teacher and pupil together in such an effective teaching environment, there can be not even the skeleton of what our times require. Hardly can it be maintained that transportation is the least essential of these items, or that it does not in fact aid, encourage, sustain and support, just as they do, the very process Which is its purpose to accomplish. No less essential is it, or the payment of its cost, than the very teaching in the classroom or payment of the teacher’s sustenance. Many types of equipment, now considered essential, better could be done without.” 330 US 1,47-48.㉔
We concur in the view that expenditures which aid a child as a pupil of a religious school cannot in that respect be regarded as serving the public welfare as *254that term is used in defining the state’s police power. The reason is stated by Mr. Justice Rutledge in his dissent in Everson v. Board of Education, 330 US 1, 53, 67 S Ct 504, 529, 91 L Ed 711, 742, 168 ALR 1392 (1946): the First Amendment “has removed this form of promoting the puib'lic welfare from legislative and judicial competence to make a public function. It is exclusively a private affair”.㉕ The dissenting opinion in Borden v. Louisiana State Board of Education, 168 La 1005, 1030, 123 So 655, 664, 67 ALR 1183 (1929) expresses the same idea: “Nor is there any room here for the application of the state’s police power. That power is not absolute and cannot be invoked to sustain legislative acts which in their operation defeat the objects and purposes of the organic law.”㉖ We are of the opinion that this analysis is correct.'
It is argued that the aid to school children is for a public purpose because the compulsory school law compels all children to attend school and that the state may, therefore, malee expenditures to further compliance. But this begs the basic question—the state may not compel compliance through the device of furnishing aid to religious schools if that aid is in violation of the constitution.㉗ Moreover, the state does not compel pupils to attend parochial schools; “their attendance upon the parochial school or private school is a matter of choice and the cost thereof not a matter *255of public concern.” Judd v. Board of Education, supra, 278 NY at 211, 15 NE2d at 582.
The theory has been advanced in some eases that since the parochial schools are performing a task which the state itself must perform through the use of the public schools, the expenditures made are not “aid” but “remuneration” for services rendered and, therefore, not prohibited by the constitutional principle of separation of church and state.㉘ The distinction is specious and its application could be urged in the justification of the expenditure of public moneys for all educational needs of parochial schools.
In the instant case the evidence establishes that the defendant school district expended approximately $4,000 for textbooks used in the St. John’s school. This constitutes a substantial benefit. The benefit is of such a character as to bring it within the proscription of Article I, § 5.
It seems obvious that as long as church and state continue to exist side by side there can not be a complete isolation of each, with neither exerting influence upon the other. It is to be expected that in the operation of the state residual benefits will accrue to the various religious groups, not because they are religious *256organizations but because they are, like other organizations, a part of the community which the state will, and must, serve indiscriminately. As Mr. Justice Black observed in the Everson case, the First Amendment (and its counterpart in state constitutions) “requires the state to be neutral in its relation with groups of religious believers and non-believers; it does not require the state to be their adversary. State power is no more to be used so as to handicap religions than it is to favor them.” (330 US 1, 18).
Neither the federal nor the state constitutions prohibit the state from conferring benefits upon religious institutions where that benefit does, not accrue to the institution as a religious organization. The proscription is against aid to religious functions. The benefits of police and fire protection, sewage disposal, and other community financed services accrue to churches not as religious organizations but as owners of property in the community.㉙ And, the same principle applies when public expenditures benefit individuals who are engaged in carrying out a religious function. A government pension paid to a clergyman for his services in the Armed Forces may benefit religion but it is not constitutionally prohibited; in such case he receives the bounty not as a cleric but as any other citizen. On the other hand, the state obviously could not pay the clergyman’s salary. The point is clearly seen by Cushman, Public Support of Religious Educa*257tion in American Constitutional Law, 45 Ill L Rev 333, 348 (1950):
“The difference between providing police protection and providing teachers does not lie in the identity of the beneficiary but 'in the way in which the aid is extended. Aid is not normally extended to individuals or institutions by name, but rather to groups or classes of individuals or institutions. Any individual or institution falling under the restrictions of the law, or falling heir to its benefits, does so only as a member of such a group. An individual may be a pupil, a pedestrian, a property owner and a parent. A church is at once a corporation, a piece of property, a building, a meeting place, a religious institution and a non-profit institution. Furthermore, a church may receive police protection when classed as property, tax exemption when classed as a non-profit institution, sewage connections when classed as a building, and yet be denied financial aid when classed as a religious institution, since such a class may not validly be given public aid. Since the aid goes to groups rather than the individual components of any one group, the eligibility of an institution to receive public aid would seem to depend on which group it is classed in, rather than on its individual characteristics.”㉚
The author then correctly concludes that where the aid is to pupils and schools the benefit is identified with the function of education and if the educational institution is religious, 'the benefit accrues to religious institutions in their function as religious institutions. And so it is in the case at bar. Granting that pupils and not schools are intended to be the beneficiaries of the state’s bounty, the aid is extended to the pupil only as a member of the school which he attends. "Whoever else may share in its benefits such aid is an *258asset to the schools themselves. State ex rel Traub v. Brown, 36 Del 181, 172 A 835 (1934). The St. John’s school shares in this benefit in a direct and vital way.㉛ We attach no significance to the fact that the books are loaned to the pnpi'l or school rather than given outright; in either event a substantial benefit is conferred upon the recipient.㉜
We recognize that whether an expenditure is an aid to a religious institution in its .religious function or in some other capacity is a question of degree. But it seems clear that the line must be drawn to 'include within the constitutional proscription the furnishing of textbooks to pupils of parochial schools. This conclusion is compelled because such books are an integral part of the educational process. As we have already pointed out, the teaching of the precepts of Catholicism is an inseparable part of the educational process in the St. John’s school. Considering the purpose of Article I, § 5, we are unable to see any substantial distinction between the furnishing of textbooks and the furnishing of blackboards, desks, laboratory instruments, or other equipment clearly necessary to the operation of the school. In comparing these various essential tools we agree with the dissenting opinion in Everson v. Board of Education of Ewing Twp., 133 NJL 350, 359, 44 A2d 33 (1945) that there is no way of “satisfactorily distinguishing one item of expense from another in the long process of child education.”
It is argued that the strict notions of separation *259in vogue at the time of the adoption of our constitutional provisions no longer exist and that these provisions should be interpreted to reflect this change in attitude.㉝ Conceding that such change has occurred, there are still important considerations warranting the resolve that the wall of separation between church and state “must be kept high and impregnable.” Everson v. Board of Education, supra, at p. 18. Among other things, the extension of aid to religious educational institutions could, as observed in Judd v. Board of Education, supra at 209, 15 NE2d at 581, “open the door for a dangerous and vicious controversy among the different religious denominations as to who should get the largest share of school funds.”㉞ More important, perhaps, is the danger that the acceptance of state aid might result in state control over religious instruction. Some religious leaders, including leaders in the Catholic church, have .opposed the acceptance of public funds on this ground.㉟ These considerations convince us that the wall of separation in this state must also be kept “high and impregnable” to meet the demands of Article I, § 5.
We are not unmindful of the fact that parents who send their children to Catholic schools must bear the double burden of supporting not only their own parochial schools but the public schools as well. But *260the added burden is self-imposed; instruction in the public schools is available to all. Catholic ¡schools operate only because Catholic parents feel that the precepts of their faith should be integrated into the teaching of secular subjects. Those who do not share in this faith need not share in the cost of nurturing it. Article I, § 5 so ordains.
Defendants argue that the denial of the use of free textbooks to pupils solely because they attend parochial schools would constitute a violation of the equal protection clause of the Fourteenth Amendment. The argument is without merit. The classification which excludes such pupils from the state’s bounty is not only reasonable, it is commanded by the constitution itself.
The principle announced in Pierce v. Society of Sisters, 268 US 510, 45 S Ct 571, 69 L Ed 1070 (1925), relied, upon by defendants, is .not germane to the problem before us. That case simply recognizes the constitutional right of a. parent to pursue freely his religious- beliefs by sending his children to parochial schools. The. court did not hold, nor was anything said in the case from which it could be implied, that the state must pay for the 'child’s education if the parent elects to use the parochial schools.
The trial’judge was of the opinion that the expenditures in question constituted a violation of the constitutional principle of separation of church and state, but he concluded that he was bound by Everson v. Board of Education, 330 US 1, 67 S Ct 504, 91 L Ed 711, 168 ALR 1392 (1946). A decision of the Supreme Court of the United States holding -that certain legislation is not in violation of the federal constitution is not an adjudication of the. constitutionality of the legislation under a state constitution. In such a case *261it is not only within the power of the state courts, it is their duty to decide whether the state constitution has been violated. Our views on the policy or interpretation of a particular constitutional provision do not always coincide with those of the Supreme Court of the United States. As we have indicated, Everson v. Board of Education, supra, is distinguishable from the ease at bar. Even if it were not, our conclusion would be the same.
The judgment is reversed. The trial court is directed to enter a decree in accordance with the prayer in plaintiffs’ complaint.
