Holy Orders is comprised of three degrees: Bishop, Priest and Deacon. This Sacrament confers an indelible mark. The Bishop possesses the fullness of the priesthood. Priests are ordained primarily to offer Mass, hear confessions and anoint the sick. And deacons are ordained to serve. Although in some cases even a married man may be ordained, only a baptized male can validly be ordained to the sacred priesthood.

How to receive this Sacrament:
Men interested in the diaconate or priesthood are invited to call one of the parish priests for counsel. By extension, any man or woman interested in the consecrated religious life is invited to speak to a priest as well. He will be able to direct you to the appropriate people for further discernment.
