It’s interesting in chapter one, after James introduces himself, when he begins actually, the letter after the introduction of himself, he says, my brethren.
He begins chapter two with the words, my brethren.
He begins chapter three with the words, My brethren, He actually uses this some eight times in this epistle. Writing to his brothers in Christ, eight times calling them, my brethren. Three more times, he calls them my beloved brethren. And four times he just speaks to them as brothers.
And so this is sort of a personal letter within the body of Christ to those brothers and sisters within the body. It’s an exhortation for the believer, My brethren, be not many masters, Now, the master, of course, was the teacher.
