The central worship service of the Orthodox Church, celebrating the Eucharist (Holy Communion).

The most common forms are the Liturgies of St. John Chrysostom and St. Basil the Great.

The morning prayer service of the Orthodox Church, traditionally celebrated at dawn. Also called Orthros in Greek tradition, this service includes the reading of the Gospel, the Great Doxology, and numerous psalms and hymns.

The evening prayer service of the Orthodox Church, traditionally celebrated at sunset. Vespers includes psalms, hymns, scripture readings, and incense.

The sacrament of healing for physical and spiritual ailments, administered by anointing with blessed oil. Also called the sacrament of anointing or Euchelaion, this service is traditionally celebrated by seven priests (though one may serve) who read seven Gospel passages and anoint the person seven times on the forehead, nostrils, cheeks, lips, chest, and hands. Holy Unction is offered not only to the dying but to all who are sick in body or soul, and many parishes celebrate it communally during Great Lent. The service emphasizes God's healing power and mercy.

Each Hour includes psalms, troparia, and prayers appropriate to that time of day. These services sanctify the day and connect us to Christ's Passion, as they commemorate specific moments in His crucifixion and death.
