And now I ask you, lady (not as [if I were] writing a new commandment to you, but [one] that we have had from the beginning), that we should love one another.

And this is love, that we should walk after his commandments. This is the commandment, even as ye heard from the beginning, that ye should walk in it.

Look to yourselves, lest we should destroy what things we have wrought, but we should receive a full reward.

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].
