Not the individual man nor a single generation by its own power can erect the bridge that leads to God. Faith is the achievement of ages, an effort accumulated over centuries. Many of its ideas are as the light of a star that left its source centuries ago. Many songs, unfathomable today, are the resonance of voices of bygone times. There is a collective memory of God in the human spirit, and it is this memory of which we partake in our faith.
