To answer the original question, ahem…
The following info about the origins of priestly celibacy is a condensed version of info from a website authored by a former nun who did extensive research into many historical traditions of the RCC.
The requirement for celibacy was begun in the middle ages. It was motivated by property inheritance customs.
The person who mentioned that it was the eldest son who entered the priesthood was right about that part. Of course it was the eldest son of the wealthy families.
The primary means to wealth in those days was land aquisition and the power it bestowed.
When the patriarch of the family died the inheritance passed to the eldest son. If the eldest son was a married priest (as it was originally) then upon his death the property passed to his son etc.
However, the church woke up to the fact that if there were no legitimate heirs, then the wealth and property was passed on to the church. The overwhelming wealth and vast land holdings of the RCC are legendary.
This also explains why the large numbers of priests (and even Popes) down through the ages who failed to keep their celibacy vows and sired numerous illegitimate children were never disciplined or expelled. Everything was just hushed up. After all, if they got kicked out, their property inheritance went with them and would not revert to the church.
As long as the kids were officially illegitimate they could not inherit. So everybody got what they wanted.
BTW yes, Paul mentions his personal choice to not marry but made it very clear that he was speaking for himself only.
And he added the caution for others “better to marry than to burn” making it clear that people shouldn’t be copycatting his choice.
The grace to live celibately is a gift of God and it’s certainly not for everyone. He expected most people to marry.
I think the primary reason the Catholic Church maintains the celibate priesthood has nothing to do with gay or straight issues at all.
For centuries they have covered over the original pecuniary motives with this facade of a superior spirituality and total dedication to God without the distraction of wife and family.
How can you back down from that lofty perch without getting egg all over your face, so to speak.
In order to be able to make a convincing argument for abandoning the celibacy requirement, they would have to make some logical case for abandoning decades of superior spirituality.
Other than coming clean about the original inheritance laws being no longer applicable to today’s customs, there is no logical position. But I don’t really see them really coming clean about this, do you.
They’ve basically painted themselves into a corner on the celibacy issue and there is just no graceful way out of it.
That’s my take on it and I think its the most logical one.
