- All we have gained then by our unbelief
Is a life of doubt diversified by faith,
For one of faith diversified by doubt;
We called the chessboard white,— we call it black.
- The fearful Unbelief is unbelief in yourself.

- In the relics of the saints the Lord Christ has provided us with saving fountains which in many ways pour out benefactions and gush with fragrant ointment. And let no one disbelieve. For, if by the will of God water poured out of the precipitous living rock in the desert, and for the thirsty Sampson from the jawbone of an ass, is it unbelievable that fragrant ointment should flow from the relics of the martyrs? Certainly not, at least for such as know the power of God and the honor which the saints have from Him.
- Alternate translation: Christ gives us the relics of saints as health-giving springs through which flow blessings and healing. This should not be doubted. For if at God’s word water gushed from hard rock in the wilderness-yes, and from an ass’s jawbone when Samson was thirsty -why should it seem incredible that healing medicine should distill from the relics of saints
