“...in contending with the corrupters of true religion, who may have the name of God continually in their mouth, and vaunt themselves on account of their observance of his outward worship, we may safely rebuke their boasting, because they do not offer the right sacrifices. But, at the same time, we must beware lest a vain pretense of godliness foster in us a perverse and ill founded confidence, in place of true hope.”
