I have no sins. I am the truth, I am the way. Anyone who says otherwise is a liar. And I shall cast the first stone.

And though sinner you may be, if you follow me, you too can then cast the first stone. You can then shame the others, while being absolve of your own sins.

Yes this is the Christian triangulation, the mind games they play on themselves and on other people, designed to puff themselves up, while attempting to weaken the resolve of others.
