"Dear friend, do not imitate what is evil but what is good. Anyone who does what is good is from God. Anyone who does what is evil has not seen God." (3 John 1:11)
Third John, also thirteen verses, is the most personal of John's letters, addressed to a named individual, Gaius, commending him for his hospitality to travelling missionaries and his faithfulness to the truth. The Elder prays that Gaius may enjoy good health even as his soul is getting along well. He rejoices greatly that Gaius walks in the truth. The missionaries he has supported have told the church about his love, and they went out for the sake of the Name, accepting no help from the pagans. The community therefore ought to show hospitality to such people so that they may work together for the truth.
In contrast, Diotrephes, who loves to be first, refuses to welcome the Elder's representatives. He is gossiping maliciously about them and expelling from the church anyone who wants to show hospitality. Dear friend, do not imitate what is evil but what is good. Anyone who does what is good is from God. Anyone who does what is evil has not seen God. Demetrius, on the other hand, is well spoken of by everyone and by the truth itself. The contrast between Gaius who walks in truth and shows hospitality, Diotrephes who loves pre-eminence and excludes the faithful, and Demetrius who is commended by truth itself, gives the tiny letter the character of a practical theology of community life. The Catechism's teaching on humility and the dangers of pride finds a concrete illustration in Diotrephes (CCC 2540).
Brothers and sisters, do not imitate what is evil but what is good. The instruction is as simple as it is demanding. Look around your community for the Gaiuses: the quiet ones who show hospitality, who give generously without seeking recognition, who walk in the truth with no need of applause. Imitate them. Avoid the spirit of Diotrephes, who loves to be first. Greatness in the Kingdom looks like Gaius, not Diotrephes.
Lord God, let us walk in truth as Gaius walked. Give us the grace of hospitality and the humility that does not need to be first. May our souls be as healthy as our bodies, and let truth itself commend us. Through Christ our Lord. Amen.
