Most visitors begin with the Divine Liturgy on Sunday morning. Some also attend Great Vespers on Saturday evening, which can be a quieter way to encounter Orthodox worship before a Sunday service.
Standing, sitting, and following along
Orthodox services involve standing, crossing oneself, bowing, processions, incense, icons, and sung prayer. Visitors are not expected to know every movement. Stand when you can, sit when needed, and follow the parish's rhythm without anxiety.
Icons and candles
Many Orthodox Christians venerate icons and light candles when they enter. Visitors may simply watch, or participate respectfully if they understand what they are doing. Icons are honored, not worshiped; worship belongs to God alone.
Holy Communion
In normal Orthodox practice, Communion is received by Orthodox Christians who are properly prepared. Visitors should not approach the chalice unless they have been received into the Orthodox Church and are blessed to commune.
After the service
Many parishes have coffee hour or a meal after Liturgy. This is a good time to meet people and ask the priest or parishioners basic questions.
Local customs differ. When unsure, ask quietly before or after the service, and do not worry about doing everything perfectly.
