"I myself follow the Church's teaching that a special exception was made for Mary the mother of Jesus.
Just WHEN did this 'teaching' begin in the Catholic Church?"
It has always been taught from the time of the apostles, although a small minority of the Church Fathers disagreed. However, it was not formally defined until 1854.
HMmmm...,P>Why so LATE??
Why at ALL, after all that time??
