3 John 1:4

“I have no greater joy, etc] Nothing that causes greater joy. The Vulgate Latin version reads “grace” or “thanks”; and then the sense is, that he had nothing to be more thankful for: than to hear that my children walk in truth; meaning his spiritual children, those whose conversion he had been the instrument of; and among these it seems Gaius was one.”

And his using this appellation, when writing under the character of the elder, has its peculiar beauty. 3 John 1:5”

“1:4 As in 2 John (see 2 Jn 1:1-4), John’s emphasis is on knowing and following the truth in contrast to Diotrephes and his followers (3 Jn 1:9).”
