That is very clearly not the reasoning behind the dogma of the Immaculate Conception.
I was refering to comments made in the thread yesterday, not official church doctrinal teachings. Mine is a summary of what i took from those comments, which I do not pretend represent the official church position.
That is the reasoning I have seen presented here and at other places.
Which has a huge logical flaw in it, in that it means that Jesus could not have walked on this earth among us. Because He would be surrounded by sin. Now I don’t know what the correct RCC statement is, but what CW stated is exactly what I have seen many Catholics post here (and quite a few have said to me).
