15. οὐκέτι. No longer do I call you servants (see on Joh 8:34 and comp. Joh 14:30. He had implied that they were His servants Joh 12:26 and stated it Joh 13:13-16. The two relationships do not exclude one another. He had called them φίλοι before this (Luk 12:4); and they did not cease to be His δοῦλοι after this (Rom 1:10; 2Pe 1:1; Rev 1:1).
ὑμᾶς δὲ εἴρ. But you have I called friends; because all things that I heard from My Father I made known to you: as they were able to bear it (Joh 16:12). After Pentecost they would be able to bear much more. Thus he who wills to do his will as a servant shall know of the doctrine as a friend (Joh 7:17).
