Orthodox priests are allowed to marry. But if you want to be a bishop you must be celibate. That is why all Orthodox bishops come from the monks. For the CC a diocesan priests takes an oath to follow the church rules not an explicit vow of celibacy. On the other hand there are the religious orders that do make explicit vows of celibacy.
More preciesly, a married man can become a Orthodox priest. A priest, deacon, and some cases a man in some lower orders, cannot marry. A widowed priest may not remarry, and some widowed priests have become bishops: for example, the Albanian Bishop Ilya, and the late Serbian Metropoliitan Christopher.
Orthodox priests are allowed to marry. But if you want to be a bishop you must be celibate.
2 A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach;
3 Not given to wine, no striker, not greedy of filthy lucre; but patient, not a brawler, not covetous;
4 One that ruleth well his own house, having his children in subjection with all gravity;
5 For if a man know not how to rule his own house, how shall he take care of the church of God?)
6 Not a novice, lest being lifted up with pride he fall into the condemnation of the devil.
7 Moreover he must have a good report of them which are without; lest he fall into reproach and the snare of the devil.
You have things a bit garbled, because, I think, you are using “celibacy” where you mean “continence.”
In the Roman Rite, all deacons promise celibacy at their ordination. This means they promise never to marry.
Since all priests and bishops are also deacons, this means that ALL clerics are bound to perfect, perpetual continence.
The obligation to perfect, perpetual continence is over and above the obligation of ALL unmarried Christians to obey the Sixth Commandment by practicing perfect continence.
Married men are allowed to become Orthodox priests.
There's a difference. ONce a man is ordained a priest, he cannot marry. If he was already married before ordination, he can remain married, but if his wife dies, he cannot re-marry.
Married ---> priest, yes
Priest ---> married, no.
