Epistle XVII. To Demetrian and Valerian. Gregory to Demetrian and Valerian, clerks of Firmum ( Fermo ). Both the ordinances of the sacred canons and legal authority permit that ecclesiastical property may be lawfully expended for the redemption of captives.  And so, since we are informed by you that, nearly eighteen years ago, the most reverend Fabius, late bishop of the Church of Firmum, paid to the enemy eleven pounds of the silver of that Church for your redemption, and that of your father Passivus, now our brother and fellow-bishop, but then a clerk, and also that of your mother, and that you have some fear on this account, lest what was given should at any time be sought to be recovered from you;—we have thought fit by the authority of this precept to remove your suspicion, ordaining that you and your heirs shall henceforth sustain no annoyance for recovery of the debt, and that no process shall be instituted against you by any one; since the rule of equity requires that what has been paid with a pious intent should not be attended with burden or distress to those who have been redeemed.
