we can drink, just not get drunk (we enjoy life without recklessness);
we can have sex, but in the context of marriage (to avoid frequent broken relationships and sexual diseases);
we can seek career success and material comfort, but not at the expense of our religious duties.
The Catholic enjoys life without making the things of this life his goal. Those who live without The Faith live in what has been called “a salt-water world”: the more we drink, the more we need: the more successful we are, the more success we seek. Thus the world’s most successful singers want more hits; the most successful sportsmen want more trophies. If today’s world does not allow the Church’s common sense into the public arena it is because the world does not seek sense, it seeks sensuality. The Catholic Church speaks up for the natural, common-sense order of things in regard to sex; for the use of our reason and will to control our base desires and passionate cravings so that our cravings do not control us.
Despite what might be claimed by some, today’s ways are not a modernisation of morality; they are a return to the morality of the ancient Greek and Roman civilisations where divorce, abortion, active euthanasia (and orthothanasia or 'passive death') and homosexuality were socially acceptable; a morality of societies that did not last -nor could they: an anti-life culture coupled with the instability of family life cannot generate a stable society.
Unless our society returns to natural sex, stability of family life and the protection and promotion of human life, today’s culture will die as did those of ancient Greece and Rome. We Catholics need only hold to our Gospel morality and wait for the time (perhaps in a few centuries) when secular society has fallen into such distress and chaos that it will seek us out to restore life and stability to a very broken and unstable world.
