The Theology In the Liturgy, by Dr. Simon Chan, p.1--
Chan writes, "Worship is essentially the response to the revelation of the triune God; it cannot be constructed arbitrarily, but must be shaped by the giveness of revelation." Chan discusses how Trinitarian theology is reflected in the liturgy and how liturgy helps us understand the triune God.    Sep/Oct 2008 Theology Matters p. 1
