Agape is one of the Koine Greek words translated into English as love, one which became particularly appropriated in Christian theology as the love of God or Christ for humankind. In the New Testament, it refers to the covenant love of God for humans, as well as the human reciprocal love for God; the term necessarily extends to the love of one.s fellow man. Many have thought that this word represents divine, unconditional, self-sacrificing, active, volitional, and thoughtful love. Although the word does not have specific religious connotation, the word has been used by a variety of contemporary and ancient sources, including Biblical authors and Christian authors. Greek philosophers at the time of Plato and other ancient authors have used forms of the word to denote love of a spouse or family, or affection for a particular activity, in contrast to Philia (an affection that could denote friendship, brotherhood or generally non-sexual affection) and eros, an affection of a sexual nature. Thomas Jay Oord has defined agape as "an intentional response to promote well-being when responding to that which has generated ill-being."
