Sallie McFague, in her book Models of God, discusses the characteristics of friendship in biblical, theological terms. Friendship does not arise from necessity. We enter into it freely. As such it represents the very essence of divine election in which God chooses to enter into relationship of friendship with Israel. Friendship is based on a disinterested love for the unique characteristics of the other. Friendship forms strong bonds and the betrayal of a friend ranks as the most dastardly of deeds. She points out that Dante reserves the inner circle of Hell for Judas, Brutus, and Cassius. (Ford, 73-74)
Then and now, friendship with Jesus brings followers into a relationship of reciprocal love, creating a community in which people who addressed each other as "friends" could realize the ideal of mutual self-sacrifice (15:12-14). (Koester, 241)
There are, as you'll see from the list below, many descriptions of who friends are and what they do, in the form of quotations and song lyrics. I find it inspiring to read them all through the lens of my best friend. After each one, I nod my head and say, "Yes, that's him all right."
