(We r not sinners. Hey Bro, we r both Buddhas—right?)
This precept approaches the same issue as Matthew does, but from a different view point.
Imagine this perspective: that both you and your brother are Buddha nature. Neither of you have a beam in your eye. In fact, both of you are as good as they come. And the "errors and faults"—that is the stuff that makes each of us real.
