Luther

God speaks through the holy prophets and men of God, as St. Peter says in his Epistle: ‘Holy men of God spake as they were moved by the Holy Ghost’. God and man must not be separated and severed from each other according to understanding and judgment of human reason; but we must immediately say, ‘Whatever this man, Prophet, Apostles, or sound preacher and teachers says and does by the command and Word of God, God Himself says and does, for he is God’s mouthpiece and instrument.’—Table-talk
