VI. Who Can Receive This Sacrament?

From The Catechism of the Catholic Church

1580
In the Eastern Churches a different discipline has been in force for many
centuries: while bishops are chosen solely from among celibates, married men
can be ordained as deacons and priests. This practice has long been considered
legitimate; these priests exercise a fruitful ministry within their
communities.⁷³ Moreover, priestly celibacy is held in great honor in
the Eastern Churches and many priests have freely chosen it for the sake of the
Kingdom of God. In the East as in the West a man who has already received the
sacrament of Holy Orders can no longer marry.
