The world cares not, but it is essential that he go and ask the Spirit to come for the sake of "justice." Otherwise, we shall be left to the fate of our own injustice.
The 15th May is Feast of St. John Baptist de La Salle C., founder of the Christian Brothers, dedicated to education of poor children. Although not commemorated in the Mass today using the 1960 rubrics, pray for a revival of true Catholic education.
