and 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.”
