And now I beseech thee, lady, not as writing to thee a new commandment, but that which we have had from the beginning, that we should love one another.

And this is love, that we walk after his commandments. This is the commandment, That, as ye have heard from the beginning, 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].
