He will depend on the Bishop for his work, placement and support in his priestly life. In general the diocesan priest will only live and work in a particular geographical area, that of his Bishop's diocese. The Diocesan priest does not take vows, but a promise of obedience to his bishop. He does not take a vow of poverty and is entitled to inherit money from family and friends. He more than often lives alone in a parish.
Most diocesan priests work as parish priests or chaplains to hospitals.
The second way of exercising priesthood is as a religious priest. This man takes vows and makes a commitment to an Order, in the person of the Provincial. He is no longer bound by a geographical location and is not directly answerable to the bishop, but to his Superior. He takes a vow of poverty which means that after final vows, whenever these are professed, he must divest himself of his own inheritance and savings. The religious priest often lives in community and has the order to support his work.
