Owen's Spiritual Worship
...while the liturgical practices of Anglicanism were of concern to Owen, he regarded the aesthetic worship of Rome as the ultimate perversion of Christian worship. Owen's own view was that worship was primarily a spiritual activity, that this spiritual activity focused upon the word preached, and that concern with increasingly elaborate aesthetics was indicative of a decreasing confidence in, and experience of, the power of the word.
