19 Neither should you think that he is father to your children who is both changeable and infirm, but you should obtain Him who is the eternal and unchanging Father of spiritual children. Assign to Him your wealth which you are saving up for your heirs. Let Him be the guardian for your children; let Him be their trustee; let Him be their protector, by His divine majesty, against all worldly injuries. The state neither takes away the property entrusted to God, nor does the exchequer intrude on it, nor does any forensic calumny overthrow it.
That inheritance is placed in security which is kept under the guardianship of God. This is to provide for one's dear pledges for the coming time; this is with paternal affection to take care for one's future heirs, according to the faith of the Holy Scripture, which says: “I have been young, and now am old; yet have I not seen the righteous forsaken, nor his seed wanting bread. All the day long he is merciful, and lends; and his seed is blessed.” And again: “He who walks without reproach in his integrity shall leave blessed children after him.” Therefore you are an unfair and traitorous father, unless you faithfully consult for your children, unless you look forward to preserve them in religion and true piety.
You who are careful rather for their earthly than for their heavenly estate, rather to commend your children to the devil than to Christ, are sinning twice, and allowing a double and twofold crime, both in not providing for your children the aid of God their Father, and in teaching your children to love their property more than Christ.
