I concur in sections I, II and III of Justice Levin’s opinion, but find it necessary to disagree with his analysis and result expressed in part IV. In my opinion supplying either school supplies or textbooks to private school students as called for in 1974 PA 242, § 18(3), violates Const 1963, art 8, § 2 [Proposal C] as previously interpreted in Traverse City School Dist v Attorney General, 384 Mich 390; 185 NW2d 9 (1971).

A. The scope of the advisory opinion.

In sections I and III of his opinion Justice Levin limits the scope of the issues under consideration in two ways. First, in section I he restricts the Court’s review to the question specifically raised by the Senate in its formal request for an advisory opinion:

“Is section 18(3) of Enrolled House Bill No. 6100 *47constitutional in relation to section 2 of Article VIII of the Constitution of Michigan, as amended, * * * ?”

Then, in section III Justice Levin eschews consideration of any other state or Federal constitutional issues which might arguably arise in the course of reviewing § 18(3) in light of Const 1963, art 8, § 2. Justice Levin states:

"Proposal C [Const 1963, art 8, § 2, second paragraph] does not speak of religion but of nonpublic schools. Proposal C, in contrast with the First Amendment, does not preclude establishment or interference with religion.

"We therefore have no need to consider whether the challenged program unduly benefits or burdens religion but only whether it directly or indirectly aids or maintains a nonpublic school.” (Footnote omitted.)

While the scope of review becomes exceedingly narrow under Justice Levin’s formulation, I believe that he has proposed a reasonable approach for the Court to follow in this advisory opinion. By definition, we are required to proceed in a factual vacuum and interpret the law without the benefits of prior fact finding and legal review. We are accordingly forced to make assumptions concerning how the questioned statute would operate once effective. I think that it is wise for the Court to therefore limit its own range of conjecture as much as possible.

B. The Constitutionality of § 18(3) under Const 1963, art 8, § 2 (Proposal C).

In Traverse City School Dist v Attorney General, 384 Mich 390; 185 NW2d 9 (1971), this Court outlined the impact of Proposal C on various types of educational assistance programs. Proceeding *48from the premise that the voters in adopting Proposal C were simply intent on outlawing parochiaid,1 the Court found it unnecessary to adopt "a strict 'no benefits, primary or incidental’ rule”.2 384 Mich 390, 413. Instead, the Court favored a reasonable construction of the amendments language. Under this construction the Court concluded that shared time programs — if properly controlled by the public school system — and auxiliary services such as health care and remedial reading programs3 could be provided to private schools consonant with the mandate of proposal C.

In my opinion the Court reached correct conclusions in the Traverse City School District case because the services examined therein were properly classified as "incidental” to a private school’s establishment and existence. (See fn 2, supra). *49Such programs as shared time and auxiliary services, to be sure, do help a private school compete in today’s harsh economic climate; but, they are not "primary” elements necessary for the school’s survival as an educational institution. These incidental services are useful only to an otherwise viable school and are not the type of services that flout the intent of the electorate expressed through Proposal C.

A very different situation is presented, I find, in the case of the textbooks and supplies that would be made available to private schools under § 18(3).4 When we speak of textbooks and supplies we are no longer describing commodities "incidental” to a school’s maintenance and support. Textbooks and supplies are essential aids that constitute a "primary” feature of the educational process and a "primary” element required for any school to exist. I quote from Bond v Ann Arbor School Dist, 383 Mich 693, 702; 178 NW2d 484; 41 ALR3d 742 (1970):

"Applying either the 'necessary elements of any school’s activity’ test or the 'integral fundamental part of the elementary and secondary education’ test, it is clear that books and school supplies are an essential part of a system of free public elementary and secondary schools.”

However Proposal C is to be construed, I believe that if the will of the electorate is to be respected it must be read to bar public funding for primary and essential elements of a private school’s existence.

*50As I understand Justice Levin’s opinion he does not actually read Proposal C differently than I do herein. He states, for example, that "Proposal C clearly bars state support of a nonpublic school’s general educational programs”; and, he points to the same language from Bond v Ann Arbor School Dist that I have quoted above. Furthermore, he reaches the conclusion that providing school supplies to private schools does violate the prohibition of Proposal C. Turning to the textbooks, however, Justice Levin, at least for the moment, reaches a different result by engrafting a new test onto the interpretation of Proposal C expressed in Traverse City School Dist v Attorney General, supra. He argues that supplying textbooks to private schools is permissible if the "dominant effect of the program is furtherance of a substantial governmental purpose, educational or noneducational, clearly distinguishable from support of general educational programs.” While I find this to be an interesting test, I do not think that it has any applicability to our present problem. Proposal C forbids the public support of private schools. I have failed to discover any indication in the language of Proposal C that the people intended to allow primary support for private schools if the private schools were willing to subject themselves to the textbook censorship of the local public school system.

C. Conclusion.

In my opinion, furnishing either textbooks or school supplies to private schools constitutes prohibited primary support under Proposal C. I would accordingly read the language of § 18(3) to apply only to public school students and thereby pre*51serve its constitutionality. Traverse City School Dist v Attorney General, supra, 384 Mich 390, 406.

(dissenting in part). By previous order,1 this Court granted the request of the Senate for an advisory opinion on the constitutionality of 1974 PA 242, § 18(3), which provides that each school district "shall purchase and loan or provide textbooks2 and supplies3 to all children of school age residing in such district and enrolled in grades 1-12” .4

The Attorney General, at the request of this Court, has briefed both sides of the question and five amicus briefs have been submitted.

A number of issues are raised.

I

We address first the scope of the issues properly before us.

The Constitution provides:

*52"Either house of the legislature or the governor may request the opinion of the supreme court on important questions of law upon solemn occasions as to the constitutionality of legislation after it has been enacted into law but before its effective date.” Const 1963, art 3, § 8.

While the challenged act states the intent of the Legislature that an advisory opinion be requested,5 the formal request from the Senate, "after it has been enacted into law but before its effective date”, states:

"The question on which an advisory opinion is hereby being sought, pursuant to Article III, section 8 of the Michigan Constitution, is as follows:

"Is Section 18(3) of Enrolled House Bill No. 6100 constitutional in relation to section 2 of Article VIII of the Constitution of Michigan, as amended, and any other relevant provision of the State or Federal Constitutions?”

Our order granting the request for an advisory opinion did not advert to whether this Court would consider questions other than those arising under the constitutional provision, Const 1963, art 8, § 2, specifically referred to by the Senate.

We recently rejected for lack of clarity a request of the Governor for an advisory opinion.6 It is not our function to search the Constitution for "any other relevant provision” which may have been violated by an act of the Legislature. In Advisory Opinion re Constitutionality of 1972 PA 294, 389 Mich 441, 484; 208 NW2d 469 (1973), we said: *53"When a court holds an act to be constitutional it does no more than deny a particular claim of unconstitutionality”. A request for an advisory opinion should "particularize any claims of unconstitutionality”.

The Attorney General and amici raise constitutional questions in addition to the specific question raised by the Senate. In Advisory Opinion re Constitutionality of 1972 PA 294, supra, p 485, we stated: "We are not, however, constitutionally authorized to furnish advisory opinions to the Michigan Trial Lawyers Association or a committee of the State Bar”. Similarly, we are not constitutionally authorized to furnish advisory opinions to the Attorney General or amici.

Accordingly, we do not consider whether the challenged act violates the Establishment Clause of the First Amendment,7 Const 1963, art 1, § 4, or the title-body clause of Const 1963, art 4, § 24.

II

While § 18(3) does not expressly require that textbooks and supplies be loaned or provided to nonpublic as well as public school children, the Senate would not have requested an opinion on the constitutionality of this provision if it were not intended that textbooks and supplies be loaned or provided to nonpublic school children. Accordingly, we reject the suggestion that we avoid the consti*54tutional question by construing § 18(3) as referring only to children attending public schools.

III

A second paragraph of Const 1963, art 8, § 2, commonly known as Proposal C, was added by vote of the people in 1970:

"No public monies or property shall be appropriated or paid or any public credit utilized, by the legislature or any other political subdivision or agency of the .state directly or indirectly to aid or maintain any private, denominational or other nonpublic, pre-elementary, elementary, or secondary school. No payment, credit, tax benefit, exemption or deductions, tuition voucher, subsidy, grant or loan of public monies or property shall be provided, directly or indirectly, to support the attendance of any student or the employment of any person at any such nonpublic school or at any location or institution where instruction is offered in whole or in part to such nonpublic school students. The legislature may provide for the transportation of students to and from any school.”

Proposal C does not speak of religion but of nonpublic schools.8 Proposal C, in contrast with the First Amendment, does not preclude establishment or interference with religion.

We therefore have no need to consider whether the challenged program unduly benefits or burdens religion but only whether it directly or indirectly aids or maintains a nonpublic school.

IV

In Bond v Ann Arbor School District, 383 Mich *55693, 702; 178 NW2d 484 (1970), this Court declared, "[I]t is clear that books and school supplies are an essential part of a system of free public elementary and secondary schools” and held that the first paragraph of Const 1963, art 8, § 29 obliged the government to provide free textbooks and supplies to students attending public elementary and secondary schools.

The act now challenged extends to nonpublic school children the provision of free textbooks and supplies.

It is contended that providing textbooks and supplies to nonpublic school children "supports the[ir] attendance” at a nonpublic school in violation of the second sentence of Proposal C. Proposal C does not seek to bar benefits to nonpublic school children, their parents and persons employed by nonpublic schools as such but, rather, benefits to children, parents and persons so employed which would subvert the purpose of the first sentence barring the use of public monies or property to aid or maintain nonpublic schools.

The challenged act subsidizes part of the cost of nonpublic school general educational programs by requiring that public school districts offer materials — textbooks and supplies — essential to those programs to children residing in the district who attend nonpublic schools. Use of the textbooks and supplies would reduce the cost of general educational programs in those nonpublic schools which theretofore provided textbooks and supplies. In schools which did not furnish textbooks and supplies, students and parents would be relieved of that cost.

*56While Proposal C clearly bars state support of a nonpublic school’s general educational programs, it does not bar all state action which tends to support such programs. This Court in construing Proposal C has eschewed "a strict 'no benefits, primary or incidental’ rule”.10 The state may exempt property of a nonpublic school from taxation and provide, without cost, police, fire and other public services.11 In Traverse City School District v Attorney General, 384 Mich 390, 417-418; 185 NW2d 9 (1971), this Court held that certain special educational and noneducational programs, known as auxiliary services, were not violative of Proposal C.12

Where a categorical program funded by the state tends to support a general educational program of a nonpublic school, it is barred by Proposal C unless the dominant effect of the program is furtherance of a substantial governmental purpose, educational or noneducational, clearly distinguishable from support of general educational programs.

We can think of no clearly distinguishable substantial governmental purpose in providing ordinary writing paper, pencils and similar consumables.

*57A nonpublic school cannot be required to adopt a textbook prescribed by the state or a school district of the state. The challenged act, by offering free textbooks, may encourage the adoption by nonpublic schools of textbooks approved by a school district of the state. To the extent nonpublic schools do adopt state or school district approved and provided textbooks, the state or school district may achieve a measure of guidance of nonpublic school instruction in the subjects for which such textbooks are adopted. The establishment and implementation of such guidance would be a substantial governmental purpose clearly distinguishable from support of general educational programs. Whether the dominant effect of providing textbooks to nonpublic school children is implementation of such a governmental purpose depends on a factual appraisal we cannot make because no factual record has been or — this being a request for an advisory opinion — could be made.

Without such a record, we cannot further advise. We have previously adverted to the limitations inherent in an advisory opinion.13 Where resolution requires a factual presentation, our advice necessarily will often be qualified by the absence of a factual predicate.

We appreciate that our construction of Proposal C in this opinion and in Traverse City, supra, requires the courts to make subtle determinations. "The argument that making 'fine distinctions’ between what is and what is not absolute under the Constitution is to render us a government of men, not laws, gives too little weight to the fact that it is an essential part of adjudication to draw distinctions, including fine ones, in the process of inter*58preting the Constitution.” Walz v Tax Commission of the City of New York, 397 US 664, 679; 90 S Ct 1409; 25 L Ed 2d 697 (1970).

We advise that 1974 PA 242 is unconstitutional insofar as it requires school districts to furnish nonpublic school children ordinary consumable supplies. Until the facts are further developed, we are not able to resolve the constitutionality of the textbook program.
