This liturgical guide offers detailed rubrics for every Sunday and major feast of the year, as well as certain lesser feasts and lenten days. The calendar also provides a list of commemorated saints and appointed scripture readings for each day of the year. The monks who came to Holy Trinity Monastery from Eastern Europe after World War II inherited a tradition of printing that stretches back almost to the invention of the printing press in the fifteenth century. Through the fathers' tireless efforts, the monastery has been printing and publishing Orthodox Christian books for almost sixty-five years. In keeping with the humble spirit required of a monk, books which are written or prepared by members of the monastic brotherhood are published under the general authorship of Holy Trinity Monastery.
