Where's your documentation of this:
Celibacy is what a priest is expected to practice, married or not.
Furthermore, celibacy is and remains a voluntary vow.
See the Holy Orders that I referenced above, given any time a priest is welcomed to the Church:
You will be required to continue in the service of God, and with His assistance to observe chastity and to be bound for ever in the ministrations of the Altar, to serve who is to reign.
The words are direct and unequivocal. Regardless of his status as married or not. The candidate is required to observe chastity.
Furthermore, celibacy is and remains a voluntary vow.
Apparently your understanding is different from the oath taken by priests during ordination. They are required to observe chastity.
Thats why that priest caught kissing a girl switched to be an Episcopal.
