Theology proper is the sub-discipline of systematic theology which deals specifically with the being, attributes and works of God.
In a Christian setting, this study includes Trinitarian, the Holy Spirit (pneumatology) and the study of Jesus Christ (Christology). The term theology (lit. 'God-word') is popularly described as 'talk about God' or God-talk, but is usually used in the generic sense to describe religious studies.
