Two days before his death, Camillus dictated his last will and testament to his confessor. Then he had seven priests sign the will and tied it to his right arm to be buried with him.

In it, he said he was letting go of all he possessed: “To the devil, I bequeath my sins against God.... To the world, I bequeath all vanities, transitory things, worldly satisfactions, empty hopes, even friends and relatives, so I may exchange what is passing for what is eternal, and all worldly curiosity for the true vision of the face of God.”
