LITURGIUM

( Gr. ) The name of a book, in the Greek Church, containing the three liturgies of St. Basil, St. Chrysostom, and that of the Presanctified , said to be composed by Pope Gregory, called Dialog us . In celebrating these three liturgies, the Greeks observe the following order. The liturgy of St. Basil, as appears by the introduction, is sung over ten times in the year; namely, on the eve of Christmas day, on the feast of St. Basil, on the eve of the feast of Lights, on the Sun days of Lent, excepting Palm Sunday, on the festival of the Virgin, and on the Great Sabbath. The liturgy of the Presanctified is repeated every day in Lent, the forementioned days excepted. The rest of the year is appropriated to the liturgy of St. Chrysostom. (See Liturgy .)
