"Whoever believes in the Son has eternal life, but whoever disobeys the Son will not see life" (Jn 3,36)
[Saint Catherine heard God say:] Know that on the final judgment day the Word my Son will come in my divine majesty to reprove the world with divine power. It will not be like when he was born in poverty, coming from the Virgin's womb into the stable among the animals, and then dying between two thieves. At that time I had my power in him to allow him to suffer pains and tortures as a man-not that my divine nature was cut off from his human nature, but I let him suffer as a man to atone for your sins. Not so will he come in this end time. Then he will come in power to reprove these people in person.
For the just it will be a cause for reverent fear and great rejoicing. Not that his face will change-for he is one with my divine nature and therefore unchangeable, and even in his human nature his face is unchangeable since it has taken on the glory of his resurrection. But it will seem so to the eyes of the damned. For they will see him with their terribly darkened vision.
A sick eye sees nothing but darkness when it looks into such lightsomeness - and it is no fault of the light that it seems so different to the two; the fault is in the sick eye. So the damned see my Son in darkness, confusion, and hatred, not through any fault of my divine Majesty with which he comes to judge the world, but through their own fault.
