Systematic theology seeks a conceptual exposition of Christian claims found throughout Scripture, in which interrelations between doctrines are traced out and the results are often ordered logically by topic. It builds itself on exegesis, biblical theology, and historical theology. Systematic theology ultimately has two topics: (1) God, and (2) everything else in relation to God. Its primary topic is God’s inner life and its secondary topic is everything else. It studies the latter by studying a particular subject as it relates back to God.
