3 John 1:1
1The elder to Gaius the beloved, whom I love in truth.
The elder to Gaius the beloved, whom I love in truth. Wesley: Caius was probably that Caius of Corinth Paul mentions (Rom 16:23)—either removed into Asia, or this letter went to Corinth. Love in the truth matches 2 John 1:1: unfeigned, holy, because of the truth.
Nothing here divides the two traditions. Gaius is named, beloved, loved in truth. The greeting is personal and already doctrinal only in that love and truth are not split.
The elder to Gaius the beloved Gaius, loved in truth. Calvin did not comment 3 John; the Johannine pair is the same as 2 John: love located in the truth, not in temperament.
A man, an elder, love that has the truth as its cause. The line raises no new point of dispute. The letter will show what that love does for brothers on the road.
