The substantive agape is mainly, if not exclusively, a Biblical and ecclesiastical word (see Deissmann, Bible Studies, 198 ff), not found in profane writings, although the verb agapan, from which it is derived, is used in classical Greek in the sense of "love, founded in admiration, veneration, esteem, like the Latin diligere" (Grimm-Thayer), rather than natural emotion (Latin, amare).
