The law judges us, as St. Paul said
Often when Paul speaks on law, he means some law in the old testament, and not the holy commandments, which the Lord gave us.
When I had been practicing faith in a protestant way (I was baptized orthodox) I felt much less guilt as believing and acting in the orthodox way. It's not the law, which condemns us. The more the light of Christ shines on your soul, the more contrition in your heart you'll feel.
