What is an Evening Divine Liturgy?
The Typikon and Triodion prescribe Vesperal Divine Liturgies of St. Basil the Great on Holy Thursday, Holy Saturday, and the paramons of Nativity and Theophany. These are not, however, what DISMISSAL refers to as an Evening Divine Liturgy (EDL). EDLs are a construction of the Antiochian Orthodox Christian Archdiocese of North America that consists of Great Vespers and the Divine Liturgy combined in a single service. The bishops of the Antiochian Archdiocese have authorized the use of EDLs for feastdays falling during the week. They are to be served on the evening before the feastday. Thus, you are prompted to flag an EDL so that the program will know which days commemoration is to be included in the dismissal.
