dissenting.

With no support beyond its own ipse dixit, the Court concludes that the Kentucky statute involved in this case “has no secular legislative purpose,” ante, at 41 (emphasis supplied), and that “[t]he pre-eminent purpose for posting the Ten Commandments on schoolroom walls is plainly religious in nature,” ibid. This even though, as the trial court found, “[t]he General Assembly thought the statute had a secular legislative purpose and specifically said so.” App. to Pet. for Cert. 37. The Court’s summary rejection of a seem lar purpose articulated by the legislature and confirmed by the state court is without precedent in Establishment Clause jurisprudence. This Court regularly looks to legislative articulations of a statute’s purpose in Establishment Clause cases *44and accords such pronouncements the deference they are due. See, e. g., Committee for Public Education v. Nyquist, 413 U. S. 756, 773 (1973) (“we need touch only briefly on the requirement of a 'secular legislative purpose/ As the recitation of legislative purposes appended to New York’s law indicates, each measure is adequately supported by legitimate, nonsectarian state interests”); Lemon v. Kurtzman, 403 U. S. 602, 613 (1971) (“the statutes themselves clearly state they are intended to enhance the quality of the secular education”); Sloan v. Lemon, 413 U. S. 825, 829-830 (1973); Board of Education v. Allen, 392 U. S. 236, 243 (1968). See also Florey v. Sioux Falls School District, 619 F. 2d 1311, 1314 (CA8) (upholding rules permitting public school Christmas observances with religious elements as promoting the articulated secular purpose of “advanc[ing] the student’s knowledge and appreciation of- the role that our religious heritage has played in the social, cultural and historical development of civilization”), cert. denied, post, p. 987. The fact that the asserted secular purpose may overlap with what some may see as a religious objective does not render it unconstitutional. As this Court stated in McGowan v. Maryland, 366 U. S. 420, 445 (1961), in upholding the validity of Sunday closing laws, “the present purpose and effect of most of [these laws] is to provide a uniform day of rest for all citizens; the fact that this day is Sunday, a day of particular significance for the dominant Christian sects, does not bar the state from achieving its secular goals.”

Abington School District v. Schempp, 374 U. S. 203 (1963), repeatedly cited by the Court, is not to the contrary. No statutory findings of secular purpose supported the challenged enactments in that case. In one of the two cases considered in Abington School District the trial court had determined that the challenged exercises were intended by the State to be religious exercises. Id., at 223. A contrary finding is presented here. In the other case no specific finding had been *45made, and “the religious character of the exercise was admitted by the State,” id., at 224.1

The Court rejects the secular purpose articulated by the State because the Decalogue is “undeniably a sacred text,” ante, at 41. It is equally undeniable, however, as the elected representatives of Kentucky determined, that the Ten Commandments have had a significant impact on the development of secular legal codes of the Western World. The trial court concluded that evidence submitted substantiated this determination. App. to Pet. for Cert. 38. See also Anderson v. Salt Lake City Cory., 475 F. 2d 29, 33 (CA10 1973) (upholding construction on public land of monument inscribed with Ten Commandments because they have “substantial secular attributes”). Certainly the State was permitted to conclude that a document with such secular significance should be placed before its students, with an appropriate statement of the document’s secular import. See id., at 34 (“It does not seem reasonable to require removal of a passive monument, involving no compulsion, because its accepted precepts, as a foundation for law, reflect the religious nature of an ancient era”).2 See also Opinion of the Justices, 108 N. H. 97, 228 A. 2d 161 (1967) (upholding placement of plaques with the motto “In God We Trust” in public schools).

The Establishment Clause does not require that the public sector be insulated from all things which may have a religious *46significance or origin. This Court has recognized that “religion has been closely identified with our history and government,” Abington School District, supra, at 212, and that “[t]he history of man is inseparable from the history of religion,” Engel v. Vitale, 370 U. S. 421, 434 (1962). Kentucky has decided to make students aware of this fact by demonstrating the secular impact of the Ten Commandments. The words of Justice Jackson, concurring in McCollum v. Board of Education, 333 U. S. 203, 235-236 (1948), merit quotation at length:

“I think it remains to be demonstrated whether it is possible, even if desirable, to comply with such demands as plaintiff's completely to isolate and cast out of secular education all that some people may reasonably regard as religious instruction. Perhaps subjects such as mathematics, physics or chemistry are, or can be, completely secularized. But it would not seem practical to teach either practice or appreciation of the arts if we are to forbid exposure of youth to any religious influences. Music without sacred music, architecture minus the cathedral, or painting without the scriptural themes would be eccentric and incomplete, even from a secular point of view. ... I should suppose it is a proper, if not an indispensable, part of preparation for a worldly life to know the roles that religion and religions have played in the tragic story of mankind. The fact is that, for good or for ill, nearly everything in our culture worth transmitting, everything which gives meaning to life, is saturated with religious influences, derived from paganism, Judaism, Christianity — both Catholic and Protestant — and other faiths accepted by a large part of the world’s peoples. One can hardly respect the system of education that would leave the student wholly ignorant of the currents of religious thought that move the world society for a part in which he is being prepared.”

*47I therefore dissent from what I cannot refrain from describing as a cavalier summary reversal, without benefit of oral argument or briefs on the merits, of the highest court of Kentucky.

A Kentucky statute requires the posting of a copy of the Ten Commandments, purchased with private contributions, on the wall of each public classroom in the State.1 Peti*40tioners, claiming that this statute violates the Establishment and Free Exercise Clauses of the First Amendment,2 sought an injunction against its enforcement. The state trial court upheld the statute, finding that its “avowed purpose” was “secular and not religious,” and that the statute would “neither advance nor inhibit any religion or religious group” nor involve the State excessively in religious matters. App. to Pet. for Cert. 38-39. The Supreme Court of the Commonwealth of Kentucky affirmed by an equally divided court. 599 S. W. 2d 157 (1980). We reverse.

This Court has announced a three-part test for determining whether a challenged state statute is permissible under the Establishment Clause of the United States Constitution:

“First, the statute must have a secular legislative purpose; second, its principal or primary effect must be one that neither advances nor inhibits religion . . . ; finally the statute must not foster ‘an excessive government entanglement with religion.' " Lemon v. Kurtzman, 403 U. S. 602, 612-613 (1971) (citations omitted).

If a statute violates any of these three principles, it must be *41struck down under the Establishment Clause. We conclude that Kentucky’s statute requiring the posting of the Ten Commandments in public school rooms has no secular legislative purpose, and is therefore unconstitutional.

The Commonwealth insists that the statute in question serves a secular legislative purpose, observing that the legislature required the following notation in small print at the bottom of each display of the Ten Commandments: “The secular application of the Ten Commandments is clearly seen in its adoption as the fundamental legal code of Western Civilization and the Common Law of the United States.” 1978 Ky. Acts, ch. 436, § 1 (effective June 17, 1978), Ky. Rev. Stat. § 158.178 (1980).

The trial court found the “avowed” purpose of the statute to be secular, even as it labeled the statutory declaration “self-serving.” App. to Pet. for Cert. 37. Under this Court’s rulings, however, such an “avowed” secular purpose is not sufficient to avoid conflict with the First Amendment. In Abington School District v. Schempp, 374 U. S. 203 (1963), this Court held unconstitutional the daily reading of Bible verses and the Lord’s Prayer in the public schools, despite the school district’s assertion of such secular purposes as “the promotion of moral values, the contradiction to the materialistic trends of our times, the perpetuation of our institutions and the teaching of literature.” Id., at 223.

The pre-eminent purpose for posting the Ten Commandments on schoolroom walls is plainly religious in nature. The Ten Commandments are undeniably a sacred‘text in the Jewish and Christian faiths,3 and no legislative recitation of a supposed secular purpose can blind us to that fact. The Commandments do not confine themselves to arguably secular matters, such as honoring one’s parents, killing or murder, *42adultery, stealing, false witness, and covetousness. See Exodus 20: 12-17; Deuteronomy 5: 16-21. Rather, the first part of the Commandments concerns the religious duties of believers: worshipping the Lord God alone, avoiding idolatry, not using the Lord’s name in vain, and observing the Sabbath Day. See Exodus 20: 1-11; Deuteronomy 5: 6-15.

This is not a case in which the Ten Commandments are integrated into the school curriculum, where the Bible may constitutionally be used in an appropriate study of history, civilization, ethics, comparative religion, or the like. Abington School District v. Schempp, supra, at 225. Posting of religious texts on the wall serves no such educational function. If the posted copies of the Ten Commandments are to have any effect at all, it will be to induce the schoolchildren to read, meditate upon, perhaps to venerate and obey, the Commandments. However desirable this might be as a matter of private devotion, it is not a permissible state objective under the Establishment Clause.

It does not matter that the posted copies of the Ten Commandments are financed by voluntary private contributions, for the mere posting of the copies under the auspices of the legislature provides the “official support of the State . . . Government” that the Establishment Clause prohibits. 374 U. S., at 222; see Engel v. Vitale, 370 U. S. 421, 431 (1962).4 Nor is it significant that the Bible verses involved in this case are merely posted on the wall, rather than read aloud as in Schempp and Engel, for “it is no defense to urge that the religious practices here may be relatively minor encroachments on the First Amendment.” Abington School District v. Schempp, supra, at 225. We conclude that Ky. Rev. *43Stat. § 158.178 (1980) violates the first part of the Lemon v. Kurtzman test, and thus the Establishment Clause of the Constitution.5

The petition for a writ of certiorari is granted, and the judgment below is reversed.

It is so ordered.
