The true doctrine respecting God and Christ
For Moses, the faithful servant of God, when he said, “The Lord your God is one Lord,” and thus proclaimed that there was only one God, did yet immediately confess also our Lord when he said, “The Lord rained upon Sodom and Gomorrha fire and brimstone from the Lord.” And again, “And God said, Let Us make man after our image: and so God made man, after the image of God made He him.” And further “In the image of God made He man.” And that [the Son of God] was to be made man [Moses shows when] he says, “A prophet shall the Lord raise up unto you of your brethren, like me.”
