Can A Christian Lose their Salvation?

Taylor Marshall of the Canterbury Tales is continuing his excellent series The Catholic Perspective on Paul. His new entry is Can a Christian lose his salvation?

I think he is often helpful. Taylor is a convert from a traditional Calvinist reformed tradition. As we continue to see what is pretty big Calvinist come back in Evangelical circles Catholics are going to need to bone up on their arguments. As I stated before in my youth TULIP , predestination ,and things like that were what the well off Presbyterians did down the street. I never met a true hardcore Calvinist Baptist till like I was 30. Times though are a changing on that front.
