The elder to a chosen‑out (selected) Lady [κυρίά: feminine of lord, owner, master], and to her children (born‑ones), whom I love in truth (truly love), and not I only, but also all those having come to know by experience, and still knowing, the Truth, because the continuously remaining (abiding; dwelling) Truth within us shall also be with us into the Age.

Grace mercy peace [= shalom]: they will be with us from beside God the Father, and from beside Jesus Christ, the Fathers Son, within Truth and Love. I was made exceedingly glad (joyful; greatly graced) because that I have met with (found) ones, out from among your children, continuously walking about within Truth, according as we took in hand a command from beside the Father. And now I am asking you, Lady, not as writing a new command to you, but one which we have had from [the] beginning (or: one which we originally had), to the intent that we may continuously be loving each other And this is Love: that we may be continuously walking about according to (down from) His commands. This is the command, even as you heard from [the] beginning (or: even which you originally heard), to the intent that you may be continuously walking about within it!

Since many wandering‑astray ones (or: many who lead astray; many deceivers) went out into the ordered system (world) ‑ those not continuously speaking like (saying the same thing as; confessing) Jesus coming in flesh: this is the one wandering astray, even the one opposite to Christ (the one instead of Christ; the one in place of Christ; antichrist) ‑ be continuously seeing yourselves (looking at yourselves), to the intent that you may not destroy (or; lose) what we did (worked), but rather may receive back full wages.

Everyone leading forward (leading in advance; [some MSS: transgressing]) and not remaining (abiding; dwelling) within Christ's teaching does not have God. the one remaining (dwelling; abiding) within that teaching, this one continuously has (holds) both Father and Son (or: the Father and the Son). If a certain one is continually coming toward you and is not carrying (bearing) this teaching, do not continually take him into a house and do not continuously say to him, "Rejoice!" [= giving him a greeting]. For the one continually telling him to be rejoicing is continually sharing in common his worthless deeds (having fellowship with his acts which bring a gush of misery; maintaining partnership with his wicked and evil works; participating in his painful, toilsome and useless works).

Having many things to write to you, I resolved not to, by means of paper and ink. For I am expecting (hoping) to come toward you and to speak mouth‑to‑mouth, to the intent  that our joy may be "having been filled!"

The children of your chosen‑out (selected) sister draw you to themselves (= greet you).
