The four tools for accurately arranging systematic theology are exegesis, biblical theology, historical theology, and contemporary theology. Exegesis involves interpreting individual biblical passages. Biblical theology examines themes across the entire Bible. Historical theology studies how Christian beliefs have developed over time. Contemporary theology applies these beliefs to current contexts.

Science does not study religion. As Stephen J. Gould says, science and religion operate, or ought to operate, in quite distinct magisteria. Science is the systematic study of the natural world, while theology is the systematic study of religion. Of course, if we regard theology as a science, then theology is the systematic study of religion and therefore of God's creation.

He obtained a Doctorate in Philosophy with a concentration in Systematic Theology from Boston University.

The two main divisions of theological study are systematic theology, which organizes beliefs in a structured manner and explores overarching themes, and practical theology, which focuses on the application of beliefs in real-world contexts such as pastoral care or social justice.
