But it is my purpose, as I reckon, and not without reason, to live according to the Word, and to understand what is revealed;[110]

If, therefore, even "an angel from heaven should preach any other gospel" (than theirs), he would be called accursed[58]

or an angel from heaven preach any other gospel."[68]
