Biblical Reference
Jesus is called advocate only once in the New Testament. This occurs in 1 John 2:1: “My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous.” The word advocate has Latin roots meaning “one who pleads for another.”
