Typica
The Typica is a part of the Divine Office of Eastern Orthodox worship and Eastern Catholic liturgy in the Byzantine Rite that is appointed to be read on any day the Liturgy is celebrated with vespers, or the Typicon does not permit the celebration of the Liturgy, or may be celebrated but is not either because no priest is present. When the Liturgy may be celebrated but is not, then the Typica is read at the time the Liturgy is appointed to be celebrated, and it contains the scriptural readings and other propers for the Liturgy.
The Typica, like the hours that it is aggregated with, is rarely read in Greek parish churches, but it is relatively common in Slavic churches.
The name "Typica" refers to the "Typical Psalms", which together with parts of the Liturgy of the Catechumens comprise the non-lenten form of the Typica.
Description
The service of Typica consists in Psalms 102 and 145, the Beatitudes, of short series of verses and hymns, the Symbol of Faith, a prayer of repentance, the Lord's Prayer, a series of appointed Kontakia, a prayer to the Trinity and Psalm 133, along with a dismissal that closely resembles that of other services.When read in place of the Liturgy's celebration, the Typica is read after the Sixth Hour in the place where the Liturgy would be celebrated; otherwise it is read after the Ninth Hour.
When replacing the Liturgy, the propers of the Liturgy are used, e.g., the troparia inserted between the verses of the Beatitudes, the kontakia after the Lord's Prayer, and the scriptural readings with their corresponding prokimena.
On the weekdays of Great Lent the Psalms are omitted and between the verses of the Beatitudes is inserted "Remember us, O Lord, when Thou comest into Thy kingdom" with small prostrations. Then the choir sings "Remember us, O Lord...; Remember us, O Master...; Remember us, O Holy..." with a great prostration. There are no readings, and, as is typical of Lenten services, the Prayer of St. Ephraim is used.
The Typica is also appointed to be read after the Royal Hours on the Eve of Nativity, the Eve of Theophany, and on Great Friday.
