Do deacons have vows

Yes, deacons in the Catholic Church do take vows, but these are typically not the same as the vows taken by priests. During their ordination, deacons make a promise of obedience to their bishop and a commitment to live a life of service, which can include a vow of celibacy if they are not married. In some other Christian denominations, deacons may also have specific commitments, but the nature of these vows can vary widely.
