Friendship in Antiquity

"The ancient concept of friendship [philia] meant far more than just a feeling of being well disposed toward someone or, in this case [alluding to James 4:4], something. The ancient ideal of friendship waas close to what we today would say about a genuine marriage. Friendship involved sharing all things in a unity that involved both the spiritual and the physical. It is even said that true friends are mia pysche ("one soul") with each other (see Euripides, Orestes 1046; Aristotle, Nicomachean Ethics 1168B)."- Ben Witherington, The Indelible Image- The Theological Thought World of the New Testament (Downer's Grover: InterVarsity Press, 2009) Vol 1, page 324.
