I think Biden did a great job articulating the pro-choice Catholic position

Making abortion illegal based on religious belief is flat out unconstitutional. The Catholic position is based on a belief that life begins at conception. We believe that the soul defines a human being, and until the 18th century there was no consensus as to when the soul entered the body with the general belief being it happened at the quickening (this seems to be the position in the Suma Theologica, as well). This idea about the quickening came from traditional Jewish teaching, which I believe most Jews still hold. So to impose a religious belief based on religious doctrine... it has no place in a nation that must respect a plurality of religions as well as the views of the non-religious.

Don't want to get into a big religious brew-ha-ha, but I just want to say that as a Catholic, I'm glad Biden did such a great job explaining the views of a pro-choice Catholic.
