All Orthodox Liturgy is basically the same. Some rituals and language is different. I know when I went to the Greek Orthodox Liturgy a few times, when our Priest was sick or out of town, it was nearly identical to the Ukrainian Orthodox.I had to ask permission of the Greek Orthodox Priest to go to communion, and it was no problem. FYI, the Byzantine Catholic Liturgy is 90% the same as the Orthodox.

Thank you for posting this ! There is nothing like Divine Liturgy, as it goes right into your soul, and brings joy !
