No man can be a Christian without having the Spirit of Christ; and if he has the Spirit of Christ, it will be manifested in kind words and a refined, courteous deportment.... External change will testify to an internal change. The truth is the sanctifier, the refiner. Received into the heart, it works with hidden power, transforming the character. But those who profess to be followers of Christ, and are at the same time rough, unkind, and uncourteous in words and deportment, have not learned of Jesus. A blustering, overbearing, faultfinding man is not a Christian; for to be a Christian is to be Christlike.... (RC 305.3) MC VC
