This is just me wondering, not saying I want this, but:
Did anyone ever notice how alot of the Saints, specially during the persecution era
were fathered by Non-Christian Fathers, but Christian Mothers:
i.e. St. Sara - whose husband was a govenrner under Diocletion, and she escaped in a boat which was about to capsize, so to save her sons lives she cut her breast and signed them with the Cross and dunked them in the water 3x...and immediately the storm subsided. Then when Pope Peter the Seal of Martyrs attempted to Baptize them he couldnt becasue her baptism was accepted.
So like when did the Church come up with the rule that we cant marry outside our religon? Or how did it come about?
