The Establishment Clause says "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof." The Establishment Clause applies to the States of the Union through the Fourteenth Amendment.

Believing with you that religion is a matter which lies solely between man and his God, that he owes account to none other for his faith or his worship, that the legislative powers of government reach actions only, and not opinions, I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should 'make no law respecting an establishment of religion, or prohibiting the free exercise thereof,' thus building a wall of separation between church and State.
Adequate restraints on abortion already exist without taking the religious views of some Christians and forcing them upon the balance of society. A July 2011 Gallup Poll found 26% of Americans think abortion should be legal under any circumstance, 51% think abortion should be legal under certain circumstances, and a minority view with 20% thinking abortion should be illegal in all circumstances.
