What is sinful about fathering a child within the bounds of holy matrimony? Do you find normal heterosexual intercourse between husband and wife sinful?
Turn, O backsliding children, saith the LORD; for I am married unto you: and I will take you one of a city, and two of a family, and I will bring you to Zion …Jesus was actually already married when He was in the flesh on the earth—to Israel, via the old covenant. His death dissolved that marriage, and the new bride is spiritual Israel, or its firstfruits.
— Jeremiah 3:14
“What is sinful about fathering a child within the bounds of holy matrimony?”
Nothing. It is only sinful for a priest to marry because he took a vow before God that he would not.
Today, some women think they can “have it all,” that they can give 100% to their kids, 100% to their husband, and 100% to their career, and still have some left over for themselves.
Clearly, when somebody sets out to give 300%, somebody else has to get short-changed.
Similarly, no man can give 100% to God and give that same 100% to a wife and family.
No one is forced to take holy orders.
Priestly celibacy is a great gift and a great blessing.
Unmarried priests are able to give more. There’s no guarantee that they will, but they can.
