A married man can receive the Sacrament of Holy Orders. That is true in both Eastern and Latin Christianity (whether the particular church is in communion with Rome or not). A man, once he has been sealed with the Sacrament of Holy Orders, may not receive the Sacrament of Matrimony. Again, both in Eastern and Latin Christianity.
As far as whether this is Biblical or not, I would ask you to show me a Biblical example of where a man who is identified as a deacon, presbyter (priest), or bishop, has been married after he has been ordained.
OK, so we agree on that so far, right?
As far as a married man receiving the Sacrament of Holy Orders, that is a matter of practice. You’ve already in earlier posts seen guidance suggesting that being single is the best way for somebody to live in the life of full-time service.
To the best of my knowledge, nobody may be ordained into the episcopate (bishop) who is married. That applies to both Eastern and Latin Christianity.
To the best of my knowledge, married men may be ordained into the diaconate (deacon) in both Eastern and Latin Christianity.
To the best of my knowledge, married men may be ordained into the presbyterate (priest) in both Eastern and Latin Christianity; however, as a matter of practice, the Latin Church does not send married men to seminary and strongly supports single men for the priesthood. As others have pointed out, though, there are dispensations granted when deemed necessary allowing married men to be ordained into the presbyterate.
But the above is a matter of practice. It is not directed in either Holy Scripture or Holy Tradition. It is a good practice, though. In fact, if you were to check with ordained people in both the Eastern and Latin Churches, I believe you’d find that it is considered a gift.
As others have pointed out, the reason why there is a shortage of priests is not celibacy, but is a narcissism that has taken over our society, including many Catholic families. This narcissism causes parents to neither display nor encourage self-sacrifice...and the one thing that is required for ordination and to have a successful ministry after ordination is a complete abandonment of self to and for Christ. It’s sort of hard to do that when one has a family to deal with.
The reason there’s a shortage of priests is that they keep replacing them with deacons, EEMs, nuns, and just about anybody who can breathe. Dioceses where there are good bishops who have a genuine understanding of who and what a priest is do not have a shortage.
This “use deacons as priests” thing is yet another attempt to push priests out the door.
Here’s a thought though... BAck in the day if a young man became a priest he made his mama proud. Would she really be proud of him for being a priest now? Have they presented an image that many young men would want to emulate? Would not a parent worry that they might be persuaded to become homosexual in Seminary or service? Is a priest of sexual age not regarded at best as an eunuch and at worst as an ipso facto homosexual?
I’m not saying the above is universal, but we need more priests like Father Corapi who would likely kick your ass if you called him a homosexual.
