Jamieson, Fausset and Brown on 3 John 1:14

14. face to face--Greek, "mouth to mouth."

Peace--peace inward of conscience, peace fraternal of friendship, peace supernal of glory [Lyra].

friends--a title seldom used in the New Testament, as it is absorbed in the higher titles of "brother, brethren." Still Christ recognizes the relation of friend also, based on the highest grounds, obedience to Him from love, and entailing the highest privileges, admission to the intimacy of the holy and glorious God, and sympathizing Saviour; so Christians have "friends" in Christ. Here in a friendly letter, mention of "friends" appropriately occurs.

by name--not less than if their names were written [Bengel].
