This statement precisely describes the tact utilized by the Court in the years following its 1947 announcement. The Court began regularly to speak of a "separation of church and state," broadly explaining that, "This is what the Founders wanted—separation of church and state. This is their great intent." The Court failed to quote the Founders; it just generically asserted that this is what the Founders wanted.
The courts continued on this track so steadily that, in 1958, in a case called Baer v. Kolmorgen, one of the judges was tired of hearing the phrase and wrote a dissent warning that if the court did not stop talking about the "separation of church and state," people were going to start thinking it was part of the Constitution. That warning was in 1958!
Nevertheless, the Court continued to talk about separation until June 25th, 1962, when, in the case Engle v. Vitale, the Court delivered the first ever ruling which completely separated Christian principles from education.
Secular Humanism
With that case, a whole new trend was established and secular humanism became the religion of America. In 1992 the Supreme Court stated the unthinkable. "At the heart of liberty is the right to define one’s own concept of existence, of meaning, of the universe, and of the mystery of human life. In 1997, 40 prominent Catholic and Protestant scholars wrote a position paper entitled, "We Hold These Truths," in which they stated, "This is the very ... antithesis --- of the ordered liberty affirmed by the Founders. Liberty in this debased sense is utterly disengaged from the concept of responsibility and community and is pitted against the ‘laws of nature and the laws of nature’s God. Such liberty degenerates into license and throws into question the very possibility of the rule of law itself.
