There is no salvation through anyone else, nor is there any other name under heaven given to the human race by which we are to be saved.
From Samuel Becket's Waiting for Godot, Act 1:
I was a high school student at Mount Saint Francis when I went with my class to a matinee presentation of Waiting for Godot at the Actor's Theater In Louisville. Father Carol Downs had prepared us for the Theater of the Absurd but the endless, aimless conversation of Didi and Gogo wasn't all that absurd to us.
We already knew in our adolescent wisdom that "The Savior" was virtually unknown; that no one of our acquaintance was afraid of going to hell; and that the Bible is full of irrelevant contradictions. In the wake of World War II, as we waited for an atomic bomb to incinerate our universe, why would anyone ask whether Jesus was taunted by one or both thieves?
How do we announce to today's Pharisee's the good news that God has raised up this Jesus whom you crucified?
The only answer to that is a lived response. I don't think there is anything we can say.
Abraham Joseph Heschl addressed this problem in his philosophy of religion, Man is not alone:
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.If we live each day as if we belong to this Church whose most ancient memories are prehistoric, others might ask the reason for your hope. Saint Peter advises us in his first letter:
Always be ready to give an explanation to anyone who asks you for a reason for your hope, but do it with gentleness and reverence, keeping your conscience clear... (I Peter 3:15)
Perhaps they will want to invest their lives in this "achievement of ages, an effort accumulated over centuries."
