Receive the Holy Spirit. Whose sins you forgive are forgiven them, and whose sins you retain are retained.’ (John 20:22-23).
At the Last Supper Jesus gave the disciples the office of the priesthood also called Holy Orders. “The ministerial priest, by the sacred power he enjoys, teaches and rules the priestly people; acting in the person of Christ, he makes present the Eucharistic sacrifice, and offers it to God in the name of all the people” (Vatican II, Dogmatic Constitution on the Church, 10). Priests offer their entire lives in service and speak the words of absolution to forgive sins in the sacrament of confession.
Holy Orders describes the sacrament which has three degrees: bishop, priest, and deacon. The fullness of Holy Orders rests in the office of bishop. Consecration as a bishop makes him a real and legitimate successor of the apostles. Priests are ordained to serve the entire Church and like the bishop exercise this ministry through the forgiveness of sins. Deacons are ordained either transitionally (as part of the path to priestly ordination) or permanently to serve at the altar and exercise the ministry of the word (preaching and teaching). They also take on specific efforts of charity, service to the sick, and pastoral care. Deacons are not ordained to forgive sins (except in the administration of Baptism) and so they cannot confect the Eucharist, hear confessions, or anoint the sick.
If you think that you might have a calling to the Priesthood or Religious Life there are plenty of good resources to find out more about what your vocation might be. A good start is usually talking to a priest that you know. Don't be afraid. It takes courage, but know that they'll never force you in any direction. They just want to help.
