And now I ask you, lady [See verse 1], not as though writing a new commandment to you, but [I wanted to remind you of] one that we had [heard] from the beginning [of Christ's ministry]: [It is] that we should love one another.

And this is [the true meaning of] love: That we should live in obedience to God's commandments. And this is the commandment, just as you heard from the beginning, that you should live in it [i.e., live a life of love].

If anyone comes to you [i.e., to your meetings] who does not bring this teaching [about Christ], you should not welcome him into your home or give him [any] greetings [i.e., suggesting approval or endorsement].
