An even better question is why are we looking into the Bible to try and see how worship should be conducted when we see little in Scripture indicating anything worship-wise? Why apply sola scriptura and ignore the fact that the early church that was persecuted, illegal, largely in catecombs and in homes, was LITURGICAL. Have you ever read the Didache? It’s a late first/early second century Church manual and it actually spells out how liturgy was conducted and it’s very similar to Catholic/Orthodox worship. It’s very structured, detailed, and says what responses should be. I highly recommend you get out of the Bible-only box, realize the Church came before the NT was even finished, and that works like the Early Church Fathers’ writings and the Didache are very important in understanding the Early Church.
And “tiresome” is all in the eye of the beholder. I say “thanks be to God” several times each week at Mass, never tire of it! I say, “Lord I am not worthy to receive you, but only say the word and I shall be healed.” The Centurian said it to Jesus, Jesus appreciated the man’s faithful words, so I have no problem saying it." I like saying the Creed. I believe it. I like saying “glory to you Lord” and the Our Father. What is so tiring about the liturgy? I suppose if you’re looking for entertainment at church and can’t say the liturgy with a heartfelt feeling then you’d be right. I believe liturgy is the only way to fly. It’s the entertainment-minded, televangelist crying and ranting and raving and arms flailing of modernity that the early Christians never exhibited. The Catholics and Orthodox have it right.
