The Admonitions VIII–AVOIDING THE SIN OF ENVY

   The apostle says: No one can say: Jesus is Lord, except in the Holy Spirit; (1 Cor 12:3) and: There is not one who does good, not even one. (Rom 3:12)

   Therefore, whoever envies his brother the good that the Lord says or does in him incurs a sin of blasphemy because he envies the Most High Himself Who says and does every good thing. (Mt 20:15)
