2 Corinthians 11:15

15 Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.

Ver. 15. As the ministers of righteousness ] Cavete a Melampygo. Try before you trust; sects and seducers are very subtle and insinuative; the locusts have faces like women; know them and avoid them. When one commended the pope’s legate at the Council of Basil, Sigismund the emperor answered, Tamen Romanus est, Yet he is a Roman. So, let Satan or his agents come never so much commended to us in his sugared allurements, let us answer, Yet he is a devil. Sin draws the devil’s picture in a man; envy is the devil’s eye, falsehood his tongue, oppression his hand, hypocrisy his cloven foot, &c.
