It was a Sunday just like any other. At the end of Mass, the priest said, “Next week, bring a non-Catholic to Mass.” I turned to my wife and whispered, “I have someone in mind.”

I had a Chinese coworker whom I will call “John.” He and I often talked about philosophical topics such as the meaning of life. At first, John was an atheist, but through our conversations, he had moved into agnosticism. Accepting Thomas Aquinas’ arguments for the existence of God wasn’t too hard for John because he often praised Aristotle, and Aquinas seemed like a continuation of Aristotle.

Discussing Aquinas was good progress in our conversational catechesis, but getting from Aquinas to Jesus seemed far off. So one day I decided to jump right to it and asked point-blank:

“Who do you say that Jesus is?” John was surprised by my question.

“My understanding is that he founded Christianity,” he responded politely, “but I need to read more about his philosophy.”

Not knowing where to go from there, I told John that I would find some material and get back to him. But I felt lost. Should I talk about the historicity of the Gospels? Should I explain that Jesus is the only person in history to be preannounced? Should I tell John that Jesus is God?

Before I could find the material that I had I promised to give John, I found myself at church, at that liturgy, with Father encouraging us to bring a non-Catholic to Mass. So, back at work, I took the plunge and said to John, “The best way to understand Jesus is by taking you to Mass next Sunday.” He didn’t hesitate to accept my invitation.

When Sunday came, I waited for John in the parking lot, and then my family and I accompanied him into the church. I could tell he was curious about the reverence parishioners showed toward the altar. As the Mass began, I waited for the priest to say something along the lines of, “Welcome all non-Catholics; I will explain the Mass.” However, he began celebrating the Mass as usual. It was a beautiful liturgy, as always, and the priest gave a wonderful homily—but he made no special mention to acknowledge any guests.
