"Some theologians restrict Chirotony (Ordination; distinct from cheirothesía/cheiróthesis,
the laying on of hands and vesting that energize a formally valid but simply potential and
not authentic or energized ordination outside of the Church and thus make it authentic
within the Church) to the "priesthood," i.e. to the hieratic orders of deacon, priest (presvýteros,
yeréfs "hiereus"), and bishop (epískopos)."
