14 But patience, beloved brethren, not only, keeps watch over what is good, but it also repels what is evil. In harmony with the Holy Spirit, and associated with what is heavenly and divine, it struggles with the defence of its strength against the deeds of the flesh and the body, wherewith the soul is assaulted and taken. Let us look briefly into a few things out of many, that from a few the rest also may be understood. Adultery, fraud, manslaughter, are mortal crimes. Let patience be strong and steadfast in the heart; and neither is the sanctified body and temple of God polluted by adultery, nor is the innocence dedicated to righteousness stained with the contagion of fraud; nor, after the Eucharist carried in it, is the hand spotted with the sword and blood.
