The fact that theology is faith seeking understanding suggests an on-going dialogue. Theology mediates between religion and the cultural matrix. It provides the channel of communication between these two realms. Theological studies provides an understanding of the resources needed to facilitate that on-going communication.
Students learn both theoretically and practically how to engage in and promote that conversation.
If religion needs the cultural matrix to keep it grounded and relevant, culture needs religion in its relentless quest for meaning. Theological studies addresses both needs.
