How do I explain the Immaculate Conception?

[mmaloque]

I am dating a Calvinist. He has been trying to understand my faith, and I struggle sometimes with the answers. He asked me where in the bible do we get the belief of the Immaculate Conception? And if God did that for Mary, why wouldn’t he do it for David, Abraham, Moses? And why did he even need to do that for Mary, when by his grace Christ didn’t need that? Would like some help answering these questions.

Hi,

It wasn’t a matter of what God the Father did for Mary, but what He did for Jesus. What so many people don’t understand is that the Immaculate Conception of Mary is all about Jesus. It was because He was to take on His human nature in her womb that she had to be free of all sin and therefore “full of grace” (Lk 1:28). It would be an abomination for Him to be conceived in a cesspool. David, Abraham and Moses weren’t called to give birth to Jesus.
