In the Byzantine Rite, (followed by the majority of Orthodox churches), the subdeacon's liturgical role is primarily that of servant to the bishop. He assists the bishop during hierarchical services, (services at which a hierarch/bishop is present and presiding) by vesting him, by looking after and presenting the trikiridikiri, placing the orletzi, operating the veil and Royal Doors, and handing the bishop and relieving him of all that he needs so as to enable him to perform his role of prayer undistracted. Outside of hierarchical services, the subdeacon serves in the altar as any other server but, as highest-ranking of the minor clergy, is responsible for co-ordinating and leading the serving team.
