There is no substitute for mastery of the principles of ritual worship. Ritual has great power to touch the human spirit. While essentially traditional, that is, handed down to us from those who have gone before, ritual is always done by living people. This is the day, the hour, of the Lord. The Scylla and Charybis of liturgical worship are formalism and trivialization.
Formalism is the repetition of gesture and word without engagement of mind, heart and soul.
We may carry out the rites in perfect accord with the rubrics, but we have not worshipped. The opposite tendency is a simple appeal to emotions by use of gimmicks. We may have perhaps made the mystery too comfortable, too casual. We have attempted to domesticate the Holy One, making for ourselves a god in our own image. This is junk food for the soul.
