This letter is from James, a slave of God and of the Lord Jesus Christ.
I am writing to the "twelve tribes"—Jewish believers scattered abroad.
Greetings! (James 1:1 NLT)
I believe this first verse says it all! James refers to himself as a slave of God and of the Lord Jesus Christ. His refering to his brother as the "Lord" should be crystal clear that the author of the New Testament that knew him best, had confidence in Jesus' divinity. Without it, no sibling would call himself a slave.
