Actually, any book that is published by
Cistercian Publications is a reliable book about both specifically Cistercianism, but monasticism in general. I especially recommend anything written by Charles Cummings, OCSO. I was loaned one of his books when I stayed a week at a convent this summer for studying.
I attend a mission that has the Divine Liturgy in a chancery chapel. There are, of course, several differences between the Byzantine and Latin Rites. The main one, I can say, is the differences between the forms of the Eucharist. It is levened and is served by intinction on a golden spoon while standing. Where I go, it is almost entirely in English, though there is an Ukrainian couple who sing some of the hymns in the Ukrainian language. Everything, except for the homily, is chanted, and everyone stands the whole time, except for the homily. The order is vaguely similar to the Latin Rite, though it is quite a bit wordier, and much more poetic. There is an opening “Lord have mercy” rite, then the epistle is chanted by a lay faithful, the gospel is chanted by the priest, then the homily. After that, is the Eucharist. That part takes about 30 minutes, with the preparatory prayer, the reception of the Eucharist, ablutions and post Communion prayers. There is the final blessing and then a final hymn to St. Thomas (who the mission is named after) is sang.
That is just a really short explaination of the Ukrainian Greek Catholic Church. Since I’m just learning, I don’t have a full understanding, but I’m sure you could search for posts and/or post on the Eastern Catholicism forum for further answers.
