There will also be Gospel readings at other occasional services from the Euchologion. His other notable works included "Trebnyk" or Euchologion (1646). The exorcism ritual, found in the "Euchologion", is that of St. Basil the Great. In the Byzantine Rite, the contents of the ritual are contained in the "Euchologion". The Euchologion was first translated into Church Slavonic in the 9th century. Thus the Euchologion is the handbook for bishops, priests, and deacons. The Euchologion contains first, directions for the deacon at the Vespers, Matins, and Divine Liturgy.
