Today's Responsorial Psalm from Psalm 130: If you, O Lord, mark iniquities, who can stand? If the Lord, who alone can take away our sins, proclaims that we are guilty, then we are guilty indeed. The Communion antiphon that came later from Ezekiel 33.11: As I live, says the Lord, I do not desire the death of the sinner, but rather that he turn back and live. We see that all we need to do is to turn back to the Lord and we shall live. We can choose to remain in our sinful state or have God take away our sins.
