A most pernicious error widely prevails that Scripture has only so much weight as is conceded to it by the consent of the church. As if the eternal and inviolable truth of God depended upon the decision of men! For they mock the Holy Spirit when they ask: Who can convince us that these writings came from God? Who can assure us that Scripture has come down whole and intact even to our very day? Who can persuade us to receive one book in reverence but to exclude another, unless the church prescribe a sure rule for all these matters? What reverence is due Scripture and what books ought to be reckoned within its canon depend, they say, upon the determination of the church. Thus these sacrilegious men, wishing to impose an unbridled tyranny under the cover of the church, do not care with what absurdities they ensnare themselves and others, provided they can force this one idea upon the simple-minded: that the church has authority in all things. Yet, if this is so, what will happen to miserable consciences seeking firm assurance of eternal life if all promises of it consist in and depend solely upon the judgment of men? Will they cease to vacillate and tremble when they receive such an answer? Again, to what mockeries of the impious is our faith subjected, into what suspicion has it fallen among all men, if we believe that it has a precarious authority dependent solely upon the good pleasure of men!
