Celibacy is the state of living without sex or marriage. A vow of celibacy, clerical celibacy, choose celibacy.
Strictly it means not marrying and in practice it means abstaining from sex, and the two senses have never quite separated. Clerical celibacy has been required of Latin Church priests since about the twelfth century and is not required in Orthodox or most Protestant traditions. Note celibate; and the distinction from asexuality, which is an orientation rather than a choice.
