The “sign of the Son of Man” (Matt. 24:30), that is, the Cross, will appear in the sky in order to proclaim the end of the present world and the coming of the eternal Kingdom of the Son of God. Then all the tribes of the earth shall weep,because they loved the present age and its lusts, but all who have endured persecution for righteousness and called on the name of the Lord shall rejoice and be glad. The Cross then will save from eternal perdition all who conquered temptations by the Cross, who crucified their flesh with its passions andl usts, and took up their cross and followed their Christ.
~ St. John of San Francisco
