Thus the Immaculate Conception. Her stainless soul was absolutely required.
If you say then that God could have made it possible, then why can you not say that God made it possible for Jesus?
If we're going to discuss "possibilities" we could also state that God could have fashioned His own flesh out of dust like He did with Adam. He didn't need to be "born" into a nuclear family, but He chose to. He chose to have a mother and a foster father and to grow and learn like all of us. Why's that? If Mary isn't worth venerating, she certainly wasn't worth being born through, right?
Totally illogical...Mary couldn't have been born 'immaculate' with parents who were soiled with sin...
Both of Mary's parents would have to have been sinless as well...
