Whenever the Catholic Church is mentioned, people's prejudices seem to overcome their ability to use logic.
Was Abraham impotent? If so, how was Ishmael conceived?
Abraham was not impotent, but Sarah was unable to conceive- hence the “borrowing” of Hagar to produce a son. According to the criteria above, the Roman Church would not have married Sarah and Abraham because the two could not produce a child. But the Lord is Great, and Sarah was able to conceive even though men thought her to be barren.
Didn’t the same thing happen with St. John the Baptist’s parents?
