“ I should think it inevitable that a public high school "endorses" a religious club, in a commonsense use of the term, if the club happens to be one of many activities that the school permits students to choose in order to further the development of their intellect and character in an extracurricular setting. But no constitutional violation occurs if the school's action is based upon a recognition of the fact that membership in a religious club is one of many permissible ways for a student to further his or her own personal enrichment. ”

“ Any incidental benefits that accompany official recognition of a religious club under the criteria set forth in the § 4071 (c) do not lead to the establishment of religion under this standard. See Widmar, supra, 454 U.S., at 273-274, 102 S.Ct., at 276. The second principle controlling the case now before us, in my view, is that the government cannot coerce any student to participate in a religious activity. ”

“ The plurality uses a different test, one which asks whether school officials, by complying with the Act, have endorsed religion. It is true that when government gives impermissible assistance to a religion it can be said to have "endorsed" religion ”
