Here is the crux of the court's opinion in that case:

"The place of religion in our society is an exalted one, achieved through a long tradition of reliance on the home, the church and the inviolable citadel of the individual heart and mind. We have come to recognize through bitter experience that it is not within the power of government to invade that citadel, whether its purpose or effect be to aid or oppose, to advance or retard. In the relationship between man and religion, the State is firmly committed to a position of neutrality. Though the application of that rule requires interpretation of a delicate sort, the rule itself is clearly and concisely stated in the words of the First Amendment. Applying that rule to the facts of these cases, we affirm the judgment in No. 142. In No. 119, the judgment is reversed and the cause remanded to the Maryland Court of Appeals for further proceedings consistent with this opinion.

It is so ordered."
