Q168. Alas! if there be so many kinds of faith that will not profit to salvation, how easy is it for me to be deceived?
It is easy indeed, and therefore the Holy Ghost doth in this thing so often caution us, 'Be not deceived'. 'Let no man deceive you', and 'If a man think himself to be something when he is nothing, he deceiveth himself'.
