If we give heed to our lives, and live long enough, we come to understand the things that eluded us earlier because of our youth and the dogmatic posture of our religious teachers. We come to know how the Yahweh-God works in the world, and we come to appreciate the dream of the Kingdom, God’s commitment to and presence in all of humankind. The divisions melt away and we finally understand the meaning of ancient Israel’s claim: “Hear O Israel, the Lord our God is one.” Once our experiences bring us to this point, we can no longer be parochial. We can longer say with conviction that one must be a Catholic. Rather, we rejoice in our own Catholicism, for we see it at its best, incarnating what the God of life has finally revealed to us in our experience, what in fact is revealed by God’s presence in all of humankind: It really doesn’t matter.
