Theology is the critical study of the nature of the divine. It is taught as an academic discipline, typically in universities, seminaries, and schools of divinity.
Theology translates into English from the Greek theologia (θεολογία) which derived from Τheos (Θεός), meaning "God," and -logia (-λογία), meaning "utterances, sayings, or oracles" (a word related to logos [λόγος], meaning "word, discourse, account, or reasoning") which had passed into Latin as theologia and into French as théologie. The English equivalent "theology" (Theologie, Teologye) had evolved by 1362. The sense the word has in English depends in large part on the sense the Latin and Greek equivalents had acquired in patristic and medieval Christian usage, although the English term has now spread beyond Christian contexts.
Augustine of Hippo defined the Latin equivalent, theologia, as "reasoning or discussion concerning the Deity";Richard Hooker defined "theology" in English as "the science of things divine". The term can, however, be used for a variety of different disciplines or fields of study.
Theology begins with the assumption that the divine exists in some form, such as in physical, supernatural, mental, or social realities, and that evidence for and about it may be found via personal spiritual experiences and/or historical records of such experiences as documented by others. The study of these assumptions is not part of theology proper but is found in the philosophy of religion, and increasingly though the psychology of religion and neurotheology. Theology then aims to structure and understand these experiences and concepts, and to use them to derive normative prescriptions for how to live our lives.
