Albert Barnes, an 19th century theologian, in his Notes on the New Testament, affirms this truth,

“If a man is not influenced by the meek, pure and holy Spirit of the Lord Jesus, if he is not conformed to His image, if his life does not resemble that of the Saviour, he is a stranger to [Christianity]… it does not matter what else he may have. He may be loud in his profession, amiable in his temper, bold in his seal or active in promoting the interest of his own party or denomination in the church; but if he does not have the character of the Saviour… it is a sounding brass or a tinkling cymbal.”
