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 […]

A Pro-Life Philosophy

Introduction Thank you. Does this [microphone] work? Can everybody hear me? If not, raise your hands. Whoever’s absent, please raise your hand. A Review of Logic A couple of preliminary rules. I’m a philosopher, I like to argue, so I’d like to say something about the role of argument in addressing an issue like abortion, and then something about the […]

What Difference Does Heaven Make?

Heaven’s Difference If a thing makes no difference, it is a waste of time to think about it. We should begin, then, with the question, “What difference does Heaven make to earth, to now, to our lives?” The answer to the question is only the difference between hope and despair in the end, between two totally different visions of life; […]

Lack of Prayer is the Cause of Lack of 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 […]

Are Human Free Will and Divine Predestination Both True?

If God is not love but only knowledge, then it is difficult or impossible to see how human free will and divine predestination can both be true. But if God is love, there is a way. Freedom and predestination is one of the most frequently asked questions among my students—partly because of modern man’s great concern for freedom, but also, […]

The Importance of Free Choice

The Role of Our Will Though agape comes from God, it resides in our free will as human beings. Its home is not the body or the feelings, or even the intellect, but the will. True, the intellect has to work with it. But it is not the intellect that loves, any more than it is the light in the operating room […]

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 […]

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 […]

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 […]

Identity — We are more than meets the eye

This thing about identity—there’s more here than meets the eye, more here than most psychologists talk about, more here than we can understand, and what I’m going to present is more questions than answers. But I think it’s a profound point, so I’ll say it. This point that our very selfhood is by nature unstable and in question, this is […]
