And then shall they see the Son of man coming in clouds with great power and glory. Mark 13:26
Today is the next-to-last Sunday of the liturgical year, before Christ the King. The readings focus on the last days: "Know that he is nigh, even at the doors.... This generation shall not pass away, until all these things are accomplished."
St. Gregory Palamas (1296-1359), a monk of Mount Athos and later Archbishop of Thessaloniki in Greece speaks of the Last Judgement:
All those who hold to true faith in our Lord Jesus Christ and show proof of their faith by good works, guarding themselves from sins or cleansing themselves from their stains by confession and repentance; who practice the virtues opposed to those sins—temperance, chastity, love, almsgiving, justice, and fair dealing—all these, I say, will rise again to hear the king of heaven himself saying to them: "Come, my Father’s blessed ones, inherit the kingdom prepared for you since the creation of the world."
So will they reign with Christ, receiving as their inheritance that heavenly kingdom which cannot be shaken, living for ever in the ineffable light that knows no evening and is interrupted by no night, having fellowship with all the saints who have lived from the beginning of time, and enjoying delights beyond description in Abraham’s embrace, where all pain has fled away, and all grief and groaning.Grant us, we pray, O Lord our God, the constant gladness of being devoted to you, for it is full and lasting happiness to serve with constancy the author of all that is good. ~ Collect at Mass
