There was a day when you could have heard it said that theologians knew nothing about the liturgy, and conversely, that liturgists knew very little theology. That misinformed attitude has disappeared, and it is now recognized that theological and liturgical studies enrich and complement one another. There cannot be two Gods—one for theologians, another for liturgists. The Church simultaneously instructs our minds through dogma and our hearts through symbol. The liturgy would be no more than exaggerated drama without roots deep in the truths theology defends and explains; and were it not for the living contact with Truth found in the liturgy, theology would be only an elaborate system of religious mathematics.

One consequence of this necessary and dynamic interaction between theology and the liturgy is that many of the problems encountered in the worship of God find their solution in theological principles.
