The 22 "sui iuris" Eastern Churches that are in union with Rome have their traditional minor orders, governed by their own particular law. In all Eastern Catholic Churches, subdeacons are minor clerics, since admission to major orders is by ordination as deacon. The Byzantine tradition allows for several orders of minor clerics. The "sui iuris" Byzantine Catholic Metropolitan Church of Pittsburgh, also called the Byzantine-Ruthenian Church, has the minor orders of candle bearer, cantor, lector and subdeacon, and in English uses the term "ordination" for their cheirothesis. The minor orders of candle bearer and cantor are given before tonsure during ordination to the lectorate.
