I didn't say it was a teaching of the Church. It's in the establishment clause.
"The most famous use of the metaphor was by Thomas Jefferson in his 1802 letter to the Danbury Baptist Association. In it, Jefferson declared that when the American people adopted the establishment clause they built a “wall of separation between the church and state.”
You also seem to forget conscience. Catholics on both the left and the right believe that "The conscience is one place that external social pressure is not allowed to violate." Here's an example:
"In late January and early February, two speakers came to Santa Clara University to speak on their experiences of Catholicism and conscience. Roy Bourgeois, laicized Maryknoll priest, recounted his personal experience of following his conscience and advocating women’s ordination. Helen Alvare, professor of law at George Mason University, told her story of fighting the US government’s Health and Human Services contraceptive insurance coverage mandate (HHS mandate)...
When placed on the right-left spectrum of Catholics (a spectrum which is, admittedly, weak at providing helpful nuance, yet is nevertheless in common use), Bourgeois and Alvare would not be mistaken for each other. Bourgeois is a hero of the Catholic “left.” He has been fighting for peace and justice issues since the war in Vietnam, he was expelled from Bolivia, he was jailed for sneaking onto Fort Benning, Georgia, he founded the School of the America’s Watch, and finally he was laicized for advocating the ordination of women to the priesthood, even doing so on Vatican Radio (before being abruptly cut off).
Alvare, on the other hand, is a hero of the Catholic “right.” She was formerly a spokeswoman of the US Conference of Catholic Bishops, and serves on Vatican committees. She opposes contraception and abortion, and is willing to argue her case in public, where she is sometimes even threatened with violence for what she says...
...Yet what most strongly united both speakers was the importance of the concept of conscience to each of them. Roy Bourgeois’ refusal to recant his opinion on women’s ordination was motivated by his conscience. Helen Alvare’s work to oppose the HHS mandate is motivated by her conscience. While the substances of their objections are different, the form is the same: conscience should not be violated."
