Bowing in the Eastern Orthodox Church
Different kinds of bows one could encounter in Eastern Orthodox service.
The First Council of Nicaea's decree "that prayer be made to God standing" from Pascha through Pentecost, and on all Sundays throughout the year, in honour of the Resurrection is strictly observed, excepting only for prostrating before the Cross on the Third Sunday of Great Lent and on the Feast of the Exaltation of the Cross, if it falls on a Sunday, as well as for a few sacramental services, e.g., ordinations.
