Religious people have a right to have their political views informed by their religion, but their right to do that ends when other people's rights begin. This is true with anybody's political views.
This is only true to the extent of compelling church attendance, forcing religious practice, etc.
Seeking a ban on abortion is seeking a ban on a practice that ends a human life. That argument can be logically made. That folks would advocate this out of religious conviction is not a reason it cannot be enacted into law.
The Supreme Court disagrees with you.
