[Since] you have purified your souls by [your] obedience to the truth [i.e., the Gospel message], which produces a genuine love for your brothers, [now] you should have this kind of fervent, heartfelt love for one another.
that person should know that whoever brings a sinner back from the error of his way will save that soul from [spiritual] death and will cover over a large number of sins [i.e., the many sins of that person will become forgiven].
If I have the ability to speak in the languages of human beings and angels [Note: Perhaps the idea is supernaturally and eloquently], but do not have love [for people], I have become [no more than] a noisy gong or a clanging cymbal.
We ought to thank God for you always, brothers, since it is proper, because your faith is growing so much and the love that every one of you has for each other is increasing more and more.
[My] dearly loved [friend], I am praying that you will do well in everything [materially (?)], and that you will have [good] health, just as your soul [i.e., your spiritual life] is doing well.
But above everything else, my brothers, do not take oaths, not “by the heaven,” nor “by the earth,” nor by any other oath. But your “yes” should be [simply] “yes,” and your “no,” [simply] “no,” so you do not fall under condemnation.
[Note: The following traits should be understood in the context of love for people]. Love is patient [with people], and is kind [to them]; love does not envy [what people are or have]; love does not boast [of being superior to others], it is not arrogant [in dealing with people].
