A friend of mine, who is a far better Christian than I can ever hope to be, once shared with me that her family sneers at her belief system and lifestyle. She believes in fairy tales they tell her. She’s looking for simple solutions from a kind-faced man in the sky because she doesn’t want to grapple with complicated answers to complicated problems.

Religion, they argue, is the easy way out. As she spoke about this, her voice became unsteady. Not with anger, but with emotion. “I would never call this life easy,” she said. “If I was looking for something that was easy, I wouldn’t choose Catholicism.”

A priest I know was asked by a door-to-door evangelist, “Do you believe in Jesus?” He answered, “Yes, I do. But if I may ask you,” he continued, “Where do you experience Jesus’ body and blood?” His interlocutor responded somewhat confusedly, “I don’t. I just believe in him. That’s all that is needed.” Later my priest friend would relate to me, “The more I thought about it, that response struck me as totally inadequate. As human beings, we need to encounter Jesus’ body and blood, not just hear about him and mentally believe. Otherwise, Jesus is just a ghost.”

This week we hear Jesus say, “He that believes in me, has eternal life” (John 6:47). These straightforward words, uttered by human lips, sound — how to put this? — insane. Who could possibly say such a thing? Jesus says things that are so high, so demanding, so beyond our capacity to fathom, we hardly know what to do with them and (if you’re like me), they usually go in one ear and out the other. So, let us ask: how can believing in him lead to eternal life?

Since my college days I’ve loved a song called “Dance with You” by the rock band Live. It touches on the deep mystical hunger of our heart: “I’ve tasted all the wines/ a half a billion times/ came sickened to your shore/ you showed me what this life is for.” These lines resonate with anyone who has feasted on the good things of this world only to be left spiritually hungover and unsatisfied.
