What are the vows said when a man becomes a priest?

Answer 1

Diocesan priests (priests that are pastors of parishes) take a promise of celibacy.

Religious priests (priests that are members of religious orders) take vows of poverty, chastity, and obedience. Some religious orders have additional vows specific to that order (e.g. the Jesuits take a vow of specific obedience to the Pope).

Answer 2

Your question is a little confused, priests do NOT make vows unless they are religious. Religious is a technical term in the Catholic Church which refers to a member of a Religious Order, like a monk, friar, nun, sister, etc. Religious make vows, that is the nature of their vocation and they make them whether they become a priest or not, in the matter of sisters and nuns, there is no possibility of them becoming priests.

Priests must have made a promise of celibacy (which is a solemn promise not to attempt marriage) but they make the promise before they are ordained to the diaconate, unless they are ordained according to the Extraordinary Form in which case, they make that promise before they are ordained to the subdiaconate.

Priests also make a promise (not a vow) of obedience to their bishop and his successors. Those are the only two promises that a priest will have to make before he is ordained.

A religious priest, however, must already be solemnly professed in his order before he makes his solemn profession. Those men, along with women who are in religious orders make three vows or promises, it's a little technical, but basically there are two different sets:

Religious who are in the Benedictine Tradition make three vows:

1) Stability

2) Conversatio Morum (roughly conversion of manners)

3) Obedience

Religious who are not in the Benedictine Tradition usually do not make vows, but promises, which may be simple, solemn, or perpetual. The three promises, which is what the person asking the question is probably looking for are:

1) Poverty

2) Chastity

3) Obedience

Jesuits, different in all things, take a fourth vow of special, immediate, and unquestioning obedience to the reigning Holy Father.
