Eastern Orthodox Church
Holy mysteries (sacraments)

The Byzantine Rite is used for the administration of the "Holy mysteries" or seven sacraments in Eastern Orthodox Christianity; among these are Holy Communion (the most direct connection), baptism, Chrismation, confession, unction, matrimony, and ordination, as well as blessings, exorcisms, and other occasions.

While the Catholic Church numbers seven sacraments, and many Protestant groups list two (baptism and the Eucharist) or even none, the Eastern Orthodox do not limit the number. However, for the sake of convenience, catechisms of the Eastern Orthodox Church will often speak of the "seven great mysteries". The term "sacrament" also properly applies to other sacred actions such as monastic tonsure or the blessing of holy water, and involves fasting, almsgiving, or an act as simple as lighting a candle, burning incense, praying or asking God's blessing on food.
