In light of my recent C.S. Lewis quote I posted, you asked how we can “dance” while avoiding “going through the motions.” The question stems from the fact that in a liturgical environment, words, phrases, and paragraphs carry enormous meaning. The fear is that this repetitive feast turns into a requiem for the dead; what some would call “empty ritualism.”
I understand your fear which is why the things we do in the church needs to be done in a highly intentional fashion. What I mean is that we need to shout our worship (Ps. 100:1) rather than whisper it. The liturgy of the Psalter, for example, was always exuberant. God speaks in a still small voice, but we are called to shout unto the Lord. We must sing vigorously, recite faithfully, and hear with great attention. When we mumble our way through the liturgy, we are saying that the “dance” is uninteresting, lacking intrigue, and a necessary check mark on a list of tedious weekly activities. But you don’t just come to church, you have the privilege of coming to church. Therefore, know the liturgy and because of that knowledge, do the act of worship with knowledge and insight and strength.
