Ordination
Ordination is the formal religious rite by which individuals are consecrated and set apart from the laity to assume roles within the clergy, granting them authority to perform specific ministerial or sacerdotal functions such as preaching, administering sacraments, or rendering religious judgments.[1][2] In Christianity, it typically involves the laying on of hands by existing clergy, a practice rooted in New Testament examples where apostles and elders commissioned deacons and overseers, signifying the transmission of spiritual authority and responsibility for church leadership.[1][3] This rite is considered essential in traditions like Roman Catholicism, where it imparts an indelible sacramental character, distinguishing it from mere recognition of gifts in many Protestant denominations.[3] Analogous ceremonies exist in Judaism as semikhah, which certifies rabbinic expertise in halakhah and authorizes legal decision-making and communal leadership, historically involving physical imposition of hands but now primarily a diploma of proficiency.[4][5] In Buddhism, ordination, known as upasampadā, initiates novices into the monastic sangha as fully ordained monks (bhikkhus) or nuns (bhikkhunis) through ritual recitation of precepts under senior monastics, emphasizing ethical commitment over hierarchical power.[6] Defining characteristics include rigorous preparation, communal affirmation, and ritual elements symbolizing divine commissioning, though debates persist over prerequisites like gender eligibility and the necessity of unbroken lineages, as seen in Catholic assertions of apostolic succession versus broader ecclesiastical validations.[3]
