1我這作長老的寫信給蒙揀選的女士1·1 學者一般認為「蒙揀選的女士」是指教會。和你的兒女，就是我本著真理所愛的。你們不單是我所愛的，也是一切認識真理的人所愛的。 2我們愛你們，因為真理在我們裡面，並且永遠與我們同在。
4你的兒女當中有人按照我們從父領受的命令遵行真理，我知道後非常欣慰。 5女士啊，我現在勸你，我們大家要彼此相愛。這不是新命令，而是我們從起初就已經領受的命令。 6愛就是遵行上帝的命令，這是你們從起初就聽過又當遵行的命令。
7因為現在世上有許多騙子出來迷惑人，他們否認耶穌基督曾降世為人。這樣的人是騙子，是敵基督者。 8你們要謹慎，好得到完滿的賞賜，免得我們前功盡棄。 9誰偏離基督的教導，誰心中就沒有上帝；誰遵守基督的教導，誰就有父和子與他同在。 10若有人到你們那裡不傳基督的教導，不要請他到家裡，也不要問候他， 11因為問候他就是與他同流合污。
1I, the elder, am writing this letter.
I am sending it to the lady chosen by God and to her children. I love all of you because of the truth. I’m not the only one who loves you. So does everyone who knows the truth. 2I love you because of the truth that is alive in us. This truth will be with us forever.
3God the Father and Jesus Christ his Son will give you grace, mercy and peace. These blessings will be with us because we love the truth.
4It has given me great joy to find some of your children living by the truth. That’s just what the Father commanded us to do. 5Dear lady, I’m not writing you a new command. I’m writing a command we’ve had from the beginning. I’m asking that we love one another. 6The way we show our love is to obey God’s commands. He commands you to lead a life of love. That’s what you have heard from the beginning.
7I say this because many people have tried to fool others. These people have gone out into the world. They don’t agree that Jesus Christ came in a human body. People like this try to trick others. These people are like the great enemy of Christ. 8Watch out that you don’t lose what we have worked for. Make sure that you get your full reward. 9Suppose someone thinks they know more than we do. So they don’t follow Christ’s teaching. Then that person doesn’t belong to God. But whoever follows Christ’s teaching belongs to the Father and the Son. 10Suppose someone comes to you and doesn’t teach these truths. Then don’t take them into your house or welcome them. 11Anyone who welcomes them shares in their evil work.
12I have a lot to write to you. But I don’t want to use paper and ink. I hope I can visit you instead. Then I can talk with you face to face. That will make our joy complete.
13The children of your sister, who is chosen by God, send their greetings.
