CSB 3 John 1:14: Peace to you. The friends send you greetings. Greet the friends by name.
mGNT 3 John 1:14: εἰρήνη σοι ἀσπάζονταί σε οἱ φίλοι ἀσπάζου τοὺς φίλους κατ’ ὄνομα
What does he mean by "Greet the friends by name"?
The Greek has κατ’ ὄνομα ("according to name") but I can't picture what that means. Does he mean "See the attached list"? Or does he want them to say "Festus, greetings from Paul". "Claudius, greetings from Paul", etc.)
Or does it simply mean "each"?
What I might have guessed from the English is "Greet the friends in my name" but the κατ’ before ὄνομα makes that unlikely.
The translations vary somewhat.
So what does the elder gentleman want Gaius to do when he says "Greet the friends by name"?
Romans 16 is full of personal greetings.
One of the names is Gaius (the same name as the recipient of the letter) who sends the following "shout out":
KJV Romans 16:23 Gaius mine host, and of the whole church, saluteth you. Erastus the chamberlain of the city saluteth you, and Quartus a brother.
