Time

Recently I was late getting a manuscript to an editor. My excuse? By far the most popular one in America: I had “no time.” Let’s examine that excuse. Why do we all seem to have no time for anything, much less for prayer? I am constantly feeling guilty about this, and I suspect most of you are too. I think […]

How the Weakness of the Cross Makes Us Strong

“When I am weak, then I am strong”; “power made perfect in weakness.” Such verses are often cited as key to spiritual growth, but do we really understand what they are talking about? Can anyone ever understand? Yes. If we couldn’t understand it at all, God would not have told it to us. God does not waste words. It is […]

Christ’s Divinity is the Key

The doctrine of Christ’s divinity is the central Christian doctrine, for it is like a skeleton key that opens all the others. Christians have not independently reasoned out and tested each of the teachings of Christ received via Bible and Church, but believe them all on his authority. For if Christ is divine, He can be trusted to be infallible […]

The Weight of Glory

We can believe we are mere mortals dreaming the dream of immortality, while in fact, we are immortals dreaming the terrible dream of mere mortality. We all know what the weight of glory is, whether or not we have read Lewis’ golden sermon. We know it from the magic words of the poets; or we know it from the wordless […]

The Feast that is the Sacraments

Four elements stand out in the traditional Catholic doctrine of what a sacrament is. Fundamentalism is suspicious of all four. A sacrament is “a sign that effects what it signifies, instituted by Christ to give grace.” 1. Sacraments are signs and symbols. Fundamentalism is temperamentally wary of symbolism. It has a plain, “no-nonsense” mentality. Symbols are too poetic for its […]

The Apple Argument Against Abortion

  Abortion Defies Common Sense I doubt there are many readers of this magazine who are pro-choice. Why, then, do I write an argument against abortion for its readers? Why preach to the choir? Preaching to the choir is a legitimate enterprise. Scripture calls it “edification,” or “building up.” It is what priests, ministers, rabbis, and mullahs try to do […]

The Winning Strategy

Editor’s Note: Dr. Kreeft’s classic essay on successfully winning the culture wars is timeless. For more information, see his book, How to Win the Culture War. To win any war, the three most necessary things to know are: (1) that you are at war, (2) who your enemy is, and (3) what weapons or strategies can defeat him. You cannot […]

The Three Most Profound Ideas I Have Ever Had

Ideas are more precious than diamonds. The three most precious ideas I have ever discovered all concern the love of God. None of them is original. But every one is revolutionary. None of them came from me. But all of them came to me with sudden force and fire: the “aha!” experience, the “eureka!” experience. They were all realizations, not […]
