The length of an Eastern Orthodox (or I guess Ukrainian C) liturgy is a related but separate issue which I was trying naïvely to ignore. Yes, it's a challenge, and the tradition-idolizing reasons for it are in fact unreasonable, and inhumane. Easterners are a mixed bag: a lot that's admirable, but a whole lot that's yucky too, e.g. self-righteousness crushing of gay rights. As Jaroslav Pelikan said, who was raised by a Lutheran father and an Orthodox mother: "The Lutherans taught me to think, and the Orthodox taught me to pray; and I'm glad it was that way, and not the other way around."

Still, not all liturgy is word-oriented, or vocal. Too much of that and you get the situation underling that old chestnut, Why don't Denomination X sing in church? --Because they're all nervously reading ahead in the hymnal, to see if they agree with the words.
