St. Paul is referring to sects which ban marriage and certain foods outright. The Catholic Church does neither - no Catholic is compelled to be celibate and no Catholic is compelled to avoid any foods.
St. Paul himself was a celibate and recommended it to others, so celibacy is not wrong or unScriptural - only compulsive celibacy is.
Likewise abstaining from certain meats - which St. Paul admits to be permissible and which St. Peter and St. James recommended - is likewise an acceptable disciplinary measure.
No Catholic is forbidden marriage or food of any kind, so as interesting as this Scriptural passage is, it simply does not apply to the Catholic Church. It applies to the groups (most likely Gnostics and Ebionites) whom St. Paul is warning his fellow Catholics against.
This is a bald-faced lie. I attended catholic school from 1-12th grades. Meat on Friday WAS FORBIDDEN. We were TAUGHT by the nuns and priests that it was a MORTAL SIN to eat meat on Friday. Any child with meat in their sandwich on Friday was sent to the Msgr.'s office.
The fact that Roman Catholic freepers continually try to claim this never happened destroys your credibility and infuriates those of us who went to catholic school and LIVED through that era.
It's akin to those who say the moon landing was faked or the Soviets re-writing the "history" books to show Russia in a better light, as though they were "FOOLING" the people who lived through the era .
