Matthew 24:30

The sign of the Son of man, &c. The Fathers generally expound this of the cross of Christ, that shall be seen in the air. (Witham) --- This sign is the cross, much more resplendent than the sun itself. Therefore the sun hides its diminished head, whilst the cross appears in glory; because the great standard of the cross, excels in brightness all the refulgent rays that dart from the meridian sun. (St. John Chrysostom, hom. lxxvii.) --- The Jews, looking upon him whom they had pierced, now coming in the clouds of heaven with power and exceedingly great glory, shall have great lamentations. Bitterly will they weep over their misery, in having despised and insulted him on a cross, who ought to have been the object of their veneration, adoration, and love. (St. John Chrysostom, hom. lxxvii.)
