To Eutyches, an Abbot of Constantinople.

Leo, the bishop, to his dearly-beloved son, Eutyches, presbyter.

He thanks him for his information about the revival of Nestorianism and commends his zeal.

You have brought to our knowledge, beloved, by your letter that through the activity of some195 Quesnel is of opinion that Eutyches’ letter had accused Domnus, Bishop of Antioch, and Theodoret, Bishop of Cyrus (cf. Lett. CXX., chapters iv. and v.), of Nestorianizing, and that he thus had gained the approbation of Leo before his own unsoundness had been made known. the heresy of Nestorius has been again reviving. We reply that your solicitude in this matter has pleased us, since the remarks we have received are an indication of your mind. Wherefore do not doubt that the Lord, the Founder of the catholic Faith, will befriend you in all things. And when we have been able to ascertain more fully by whose wickedness this happens, we must make provision with the help of God for the complete uprooting of this poisonous growth which has long ago been condemned. God keep thee safe, my beloved son. Dated 1st June, in the consulship of the illustrious Postumianus and Zeno (448).
