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

Leo, the bishop, to his dearly beloved son, Eutyches [a prominent monk and abbot in Constantinople], presbyter.

Your letter has brought to our attention, beloved, that through the efforts of certain individuals, the heresy of Nestorius [the teaching that Christ existed as two separate persons — one divine, one human — condemned at the Council of Ephesus in 431] has been reviving again. We want you to know that your concern in this matter has pleased us, since the observations we received reveal the quality of your convictions. Therefore, do not doubt that the Lord, the founder of the Catholic Faith, will support you in all things. And when we have been able to determine more precisely whose wickedness is behind this, we must take steps, with God's help, to completely uproot this poisonous growth that was long ago condemned. God keep you safe, my beloved son. Dated June 1, in the consulship of the illustrious Postumianus and Zeno (448).
