Fr Dwight Longnecker has a beautiful meditation on why today's feast immediately follows the feast of the Exhaltation of the Holy Cross. Our Lady leads us by her example of sharing in the suffering of Our Lord, we follow her, carrying our crosses. See the beautiful collection of Marian art at Salve Regina.
I have friends who carried the contents of their desks out the door of Lehman Brothers in New York today. Please pray that they may see their current suffering as an opportunity to make up what is lacking in the suffering of Christ, and to trust their futures to Christ's mercy.
