Dear Brethren, these are the two groups that appear before you each day, the followers of Christ and the followers of the world…
To the right, the little flock that follows Jesus can speak only of tears, penance, prayer and contempt for worldly things… Worldlings, on the contrary, rouse one another to persist in their unscrupulous depravity. “Enjoy life, peace and pleasure,” they shout, “Enjoy life, peace and pleasure. Let us eat, let us drink, let us sing, let us dance, let us play. God is good, He did not make us to damn us; God does not forbid us to enjoy ourselves; we shall not be damned for that; away with scruples; we shall not die.” …
In answer to the gracious invitation which Jesus extends, let us rise above ourselves… Let us look up to the unique Author and Finisher of our faith, Jesus crucified. Let us fly from the corrupting concupiscence and enticements of a corrupt world. Let us love Jesus in the right way, standing by Him through the heaviest of crosses. Let us meditate seriously on these remarkable words of our beloved Master… “If any man will come after Me let him deny himself, and take up his cross, and follow Me”.
