Antichrist

Antichrist is the more deceitful in that he professes Jesus Christ with the mouth but denies Him by his actions. Augustine

Now anyone who has learned from Scripture what are the things that belong particularly to God, and who on the other hand considers well what the Pope usurps for himself, will not have much difficulty in recognising Antichrist, even though he were a ten-year-old boy. Calvin

The Scriptures portray Antichrist not merely as contrary to Christ but as a mock Christ. M.E. & F.A. Markham
