what is the difference between priest and bishop
Hierarchy of the Catholic Church All clergy, including deacons, priests, and bishops, may preach, teach, baptize, witness marriages, and conduct funeral liturgies.[10] Only priests and bishops can celebrate the sacraments of the Eucharist (though others may be ministers of Holy Communion),[11] Penance (Reconciliation, Confession), Confirmation (priests may administer this sacrament with prior ecclesiastical approval), and Anointing of the Sick.[12][13] Only bishops can administer the sacrament of Holy Orders, by which men are ordained as bishops, priests or deacons.[14]
Hierarchy of the Catholic Church The hierarchy of the Catholic Church consists of its bishops, priests, and deacons.[1][2] In the ecclesiological sense of the term, "hierarchy" strictly means the "holy ordering" of the Church, the Body of Christ, so to respect the diversity of gifts and ministries necessary for genuine unity. (1 Cor 12)
