"Stop judging, that you may not be judged.
For as you judge, so will you be judged,
and the measure with which you measure will be measured out to you.
Why do you notice the splinter in your brother's eye,
but do not perceive the wooden beam in your own eye?
How can you say to your brother,
'Let me remove that splinter from your eye,'
while the wooden beam is in your eye?
You hypocrite, remove the wooden beam from your eye first;
then you will see clearly
to remove the splinter from your brother's eye."
-- Mt 7:1-5
Following in the steps of the prophets and John the Baptist, Jesus announced the judgment of the Last Day in his preaching. Then will the conduct of each one and the secrets of hearts be brought to light. Then will the culpable unbelief that counted the offer of God's grace as nothing be condemned. Our attitude to our neighbor will disclose acceptance or refusal of grace and divine love. On the Last Day Jesus will say: "Truly I say to you, as you did it to one of the least of these my brethren, you did it to me."
-- CCC 678
