What is the difference between a diocesan priest and a priest from a religious order?
A diocesan priest makes a promise of obedience to a diocesan bishop and serves a particular parish, or diocese. He lives a celibate life detached from material possessions but does not take a vow of poverty. Priests and brothers in religious orders profess vows of poverty, chastity and obedience. Marianists also profess the vow of stability, which reflects their special devotion to Mary. Priests in a religious order serve the particular needs of that order.
