From today's First Reading from the First Book of Maccabees:
In those days there appeared in Israel men who were breakers of the law,
and they seduced many people, saying: “Let us go and make an alliance with the Gentiles all around us; since we separated from them, many evils have come upon us.” The proposal was agreeable;some from among the people promptly went to the king, and he authorized them to introduce the way of living of the Gentiles. Thereupon they built a gymnasium in Jerusalem according to the Gentile custom. They covered over the mark of their circumcision and abandoned the holy covenant; they allied themselves with the Gentiles and sold themselves to wrongdoing.
In those days, the People of God (of course not all) sold out to the world. They turned from God to the world and its prince. They drunk deeply from the fountain of popular culture and poisoned their souls. Shame on them.
But lest we shake of fingers at those of the past, we need to realize that we have done the same thing. Over the last forty-five years or so, too many Catholics when confronted with opposition to the Faith from culture and the world have chosen the later. And more is the pity, they have done so with the aid of many theologians, lay 'leaders', and clergy using a mis-interpretation of the Second Vatican Council. Why is our understanding of human sexual so out of sync with the Gospel? We have allowed ourselves to be catechized by Hollywood. (If I hadn't believed this before, the recent "Rent" fiasco proved it once and for all.) Too many of the clergy and yes that includes the higher clergy, have deferred to so-called experts both in theology and secular sciences and have sold out the Gospel. Need an example of this, look at the Homosexual Abuse Scandal among the clergy.
The point is that the world must be conformed to the Gospel. We must be conformed to the Gospel. We must not allow ourselves to be evangelized by the anti-Gospel of the world.
