Euchologion

Semi-Autonomous: The Euchologion (Greek: Εὐχολόγιον; Slavonic: Трeбник, Trebnik;[1] Romanian: Euhologiu/Molitfelnic) is one of the chief liturgical books of the Eastern Orthodox and Byzantine Catholic churches, containing the portions of the services which are said by the bishop, priest, or deacon.

The ceremonies for tonsuring monks or nuns come next, the appointing of a priest to be confessor (pneumatikos) and the manner of hearing confession, prayers to be said over persons who take a solemn oath, for those who incur canonical punishments, and for those who are absolved from them.

Next, consecrations for new churches and antimensia (the corporal containing relics used for the Divine Liturgy; it is really a kind of portable altar), the ceremony of washing the altar on Holy Thursday, erection of a Stauropegion (a monastery that is exempt from the control of the local bishop, being instead subject directly to the Patriarch or Synod of Bishops), the Lesser Blessing of Waters (hagiasmos), and the Great Blessing of Waters (used on Theophany), followed by a sacramental which consists of bathing (nipter) afterwards.

Then follows a miscellaneous collection of prayers and hymns (marked euchai diaphoroi), Canons of penance, against earthquakes, in time of pestilence, and war, and two addressed to the Theotokos.

In modern Euchologia, however, it is usual to add the "Apostles" (the readings from the Epistles) and Gospels for the Great Feasts (these are taken from the two books that contain the whole collection of liturgical lessons), and lastly the arrangement of the court of the Ecumenical Patriarch, with rubrical directions for their various duties during the Liturgy.

It contains only the short responses of the choir, who have their own choir-books (Horologion for the fixed portions of the services, and the Triodion, Pentecostarion, Octoechos and Menaion for the propers).

This edition contains some 20 rituals that were of local origin and are not performed in other Eastern churches (e.g., services for the uncovering of holy relics and for the blessing of monasteries).

Greek-Catholics use the Propaganda edition and have a compendium (mikron euchologion) containing only the Liturgies, Apostles and Gospels, baptism, marriage, unction, and confession (Rome, 1872).
