Letters of the Blessed Theodoret,
LI. To the Presbyter Agapius.
The works of virtue are admirable in themselves, but yet more admirable do they appear if they find an eloquence able to report them well. Neither of these advantages has been lacking in the case of the bishop beloved of God, the lord Thomas, for he himself has contributed his own labours on behalf of piety, and has found in your holiness a tongue to bestow meet praise on those labours. Coming as he did with such testimony in his favour we have been all the more delighted to see him, and, after enjoying his society for a short space, have dismissed him to his charge.
 Neither Agapius nor the bishop mentioned in this letter can be identified.
