n.; pl. Theologies [ L. theologia, Gr. &unr_;; &unr_; God + &unr_; discourse: cf. F. théologie. See Theism, and Logic. ] The science of God or of religion; the science which treats of the existence, character, and attributes of God, his laws and government, the doctrines we are to believe, and the duties we are to practice; divinity; (as more commonly understood) “the knowledge derivable from the Scriptures, the systematic exhibition of revealed truth, the science of Christian faith and life.” [ 1913 Webster ]

Many speak of theology as a science of religion [ instead of “science of God” ] because they disbelieve that there is any knowledge of God to be attained. Prof. R. Flint (Enc. Brit.). [ 1913 Webster ]

Theology is ordered knowledge; representing in the region of the intellect what religion represents in the heart and life of man. Gladstone. [ 1913 Webster ]
