Systematic theology is a branch of theology that attempts to organise (or "systematise") religious truth into a categorical system. Within evangelical Christianity, systematic theology organises the Bible's teachings into a system of topics, ranks them in importance, and shows the interrelationships within each of the topics.

Topics within systematic theology can be classified in two broad categories: (a) topics that are raised by the Bible itself (e.g. the nature of the Trinity), and (b) topics that are raised by people (e.g. what does the Bible say about work?). While (a) is generally easier to work with, by virtue that the Bible says a lot about it for it to be a topic, (b) is more common in practice, not least because of apologetics.

The development of a systematic theology on a particular topic is a science, as it uses a form of the scientific method. A hythothesis about the topic is formulated, and then tested with biblical data. If the hypothesis is found wanting, it is rejected and a new hypothesis developed. If the hypothesis fits with all of the biblical data, then it is accepted.

Examples of Systematic-Theological Classifications

Examples of such classifications are generally found in two sources:
