It's just very ritualistic and planned out especially Catholic church. Hyms are the same songs for sometimes centuries old, kneel at the same time, say the same things together, etc. the organization isn't planning, it's ritual.
Black (baptist, AME, etc) church's were built on the ritual being the get together itself, and the time for that is less important than the emotion/feeling/worship around it. I damn near missed a Superbowl once because of the opening of a new church sanctuary and service. But, I stream the same church to this day and I tune in at exactly 8am PST because regardless of everything else, pastor starts the sermon then (ministry of music honestly does little for me).
But, not saying it's right, fair, or modern, but in black churches, it's a testament to your faith:
You got something BETTER to do than worship
