2 John New American Bible (Revised Edition) (NABRE)
1 [a]The Presbyter to the chosen Lady and to her children whom I love in truth—and not only I but also all who know the truth— 2 because of the truth that dwells in us and will be with us forever. 3 Grace, mercy, and peace[b] will be with us from God the Father and from Jesus Christ the Father’s Son in truth and love.
4 I rejoiced greatly to find some of your children[c] walking in the truth just as we were commanded by the Father. 5 But now, Lady, I ask you, not as though I were writing a new commandment but the one we have had from the beginning: let us love one another. 6 For this is love, that we walk according to his commandments;[d] this is the commandment, as you heard from the beginning, in which you should walk.
7 Many deceivers have gone out into the world, those who do not acknowledge Jesus Christ as coming in the flesh; such is the deceitful one and the antichrist.[e] 8 Look to yourselves that you[f] do not lose what we worked for but may receive a full recompense. 9 Anyone who is so “progressive”[g] as not to remain in the teaching of the Christ does not have God; whoever remains in the teaching has the Father and the Son. 10 [h]If anyone comes to you and does not bring this doctrine, do not receive him in your house or even greet him; 11 for whoever greets him shares in his evil works.
12 [i]Although I have much to write to you, I do not intend to use paper and ink. Instead, I hope to visit you and to speak face to face so that our joy may be complete. 13 The children of your chosen sister[j] send you greetings.
