We need a homily on 1 Epistle of John, not Gospel of John.
In fact, the distinction can only be inferred from St. Augustine; 1 John makes it but does not elaborate much.
"We need a homily on 1 Epistle of John, not Gospel of John."
Well that would explain why when I read 1 John v, I didn't see what you were talking about and of course +John Chrysostomos didn't write on that epistle. Sorry.
