Deuteronomy 25:7

Verse 7. But if the kindred good be unwilling to be conjoined to the truth of the lost good—i.e. if spiritual good be unwilling to flow forth and manifest itself in the natural life— let natural truth appeal to the primary doctrines of the Church relating to the state of communication between the spiritual and natural mind, as to the fact that spiritual good refuses to perform deeds of natural charity, and to flow forth into the natural life.
