17. When orthodoxy enters and explains those things which the priests preach from the Word concerning faith, that we must believe in God; concerning charity towards the neighbour; concerning conversion; concerning repentance, and hence the life of piety and spirituality-all these things fall, as it were, into a bucket; and then they are overthrown, as when men destroy a building, or house, so that nothing remains but ruins: and then they say, "These things are not truths unless you so believe. What does charity matter? or repentance?" etc. The very Word then falls to the ground, etc. It is as if one undermines a wall by digging ditches under it. All things are overthrown.
