...although it is doubtless true that the entire range of ἀγαπάω (agapaō, to love) and the entire range of φιλέω (phileō, to love) are not exactly the same, nevertheless they enjoy substantial overlap; and where they overlap, appeal to a “root meaning” in order to discern a difference is fallacious. In 2 Samuel 13 (LXX), both ἀγαπάω (agapaō, to love) and the cognate ἀγάπη (agapē, love) can refer to Amnon’s incestuous rape of his half sister Tamar (2 Sam. 13:15, LXX). When we read that Demas forsook Paul because he loved this present, evil world, there is no linguistic reason to be surprised that the verb is ἀγαπάω (agapaō, 2 Tim. 4:10). John 3:35 records that the Father loves the Son and uses the verb ἀγαπάω (agapaō); John 5:20 repeats the thought, but uses φιλέω (phileō)—without any discernible shift in meaning. The false assumptions surrounding this pair of words are ubiquitous... My only point here is that there is nothing intrinsic to the verb ἀγαπάω (agapaō) or the noun ἀγάπη (agapē) to prove its real meaning or hidden meaning refers to some special kind of love.
