The Latin quote must've derived from the Roman Church and its Vatican/papacy according to my Lutheran catechism they clearly have it backwards. Besides, using the same liturgical forms week after week after week can be reduced to mindlessly reciting memorized passages without any focus on their worshipful meanings. I did so for 52 years and while closed communion drove us to another LCMS parish practicing no such thing, we also discovered the immense and beautiful variety of God-pleasing and faithful worship hymns and styles. I can never "fall asleep" as things change ever week while faithfully retaining the format of the liturgical order of Divine Service. We skip nothing and anyone ever witnessing our baptisms would never go back to the rote verbiage of the hymnal's version. Which, by the way, has changed at least three times in my lifetime and much of it derives from the Church of Rome. A faithful & now departed pastor of the LCMS once advised me and our Elders that today's society blocks out its daily schedules on an hourly basis and not respecting that will have some folks look for other worship opportunities or even denominations. In the end, I appreciate and can worship to LH/LWB/LSB's liturgical orders but not every week. I need the variety of contemporary formats to keep my mind focused on God. God bless you if you do not ever encounter this challenge but please stop dividing the Body of Christ over yet another item of the adiaphora. We need to battle Satan, not each other.
