As for "religious protection"....not so much.
The word “God” does not appear in either of the founding documents. The words “...their Creator...” appears in the Declaration of Independence and is only referred to in the Constitution. Christians who claim that the founding Fathers that wrote the clause “...that they are endowed by their Creator...” was referring to the Christian-Judeo God. However, one of the major tenets of the founding of the US of A was religious persecution and that any religion could be practised without persecution by the government.
If Satanists believe their Creator is a God they call Satan, then they are free to practise their beliefs in the US of A. However, that right stops when their right to practise infringes on the rights of another. Abortion is a right, not settled law, given by SCOTUS to the the citizens of the US. Abortion is the denial of rights by the unborn for the mother to practise her rights as set forth in the founding documents of the US of A. The practise of abortion as a right does not include or preclude religious rights. Since being pregnant only infringes on another in certain life or death cases, it cannot be said that carrying an unborn child and the willful termination of an unborn baby is denying a right because it does not infringe upon the rights of another; therefore, since it does not infringe on the right of the free practise of religion, abortion is not a right under the First Amendmendment. In other words, abortion is not a right under the right of freedom of religion clause. But a demonrat appointed or left leaning judge will see otherwise.
