That is precisely why; marriage after ordination is against Canon Law (Church Law).
Yes, thank you, as noted I am aware of that fact, I was asking about the underlying theological reason for this legal fact.
It is a discipline of the Catholic church and the Orthodox Church as well.
Yes, thanks for that, I know. I was asking about the theological reasoning behind the discipline.
If a married priest or deacon has a wife who dies, the man is now single. Single men are not allowed to marry after ordination.
Yes, thanks for pointing that out, I'm aware it is not allowed. I was asking about the theology underpinning this fact.
The reason why a ordained man cannot marry after ordination is simply because the Church has chosen it to be that way.
Thanks, I appreciate the response. Are you certain there is no theological reason at all? That's what I'm asking about.
An unmarried priest is available to be sent anywhere in the world at an hour's notice. Try doing that with a married man!
Yes, this is a good and well-known argument for priestly celibacy. However, I'm not sure this answers my question....if it did, wouldn't it simply be a reason not to admit married men to ordination at all?
They make a vow to remain celibate should their spouse predecease them.
Thanks, I'm aware that this is the current practice in the Roman Church...although as noted by some other posters here (and at least in our diocese) married men do not respond to this question by the Bishop during the ordination of deacons and so don't technically take this vow. However, their vow of obedience would suffice since since this is current practice everywhere.
However, if his marriage terminates natually (i.e., by the death of his wife), he is held to the same standard that any (unmarried) man is held to at the time of his ordination: no marriage following ordination.
Thanks for the reply. Yes he is. I am wondering why this is true.
As I noted in the OP, I have attempted to ask this before in other venues. I have never been able to get it phrased correctly to help people to work on the question I really have in mind. I'll try once more.
The disciplines of the Catholic Church usually have reasons behind them. I'm looking for this discipline's reason. It would seem that in the judgement of the Church, a man being married does not reduce his chance of success as a deacon, since so many married men are ordained deacons in many nations. If marriage is a good, and it does not interfere with the discharge of duties of a deacon, then what possible reason for preventing another marriage could there be?
Maybe there is none, I am aware that this is a possibility. If there is none, I would be interested to know that.
Thanks to everyone who responded.
