ordination (n.)

c. 1400, ordinacioun, "divine decree;" early 15c., "arrangement, putting in order," also "the act of admitting to holy orders or the Christian ministry" (the main surviving sense), from Old French ordinacion (12c.) or directly from Latin ordinationem (nominative ordinatio) "a setting in order, ordinance," noun of action from past participle stem of ordinare "to put in order, arrange, dispose, appoint," from ordo (genitive ordinis) "row, rank, series, arrangement" (see order (n.)).
