“Jesus had just said something that upset and offended his audience and the gospels tell us that everyone walked away grumbling that what Jesus was teaching was “intolerable”. Jesus then turns to his apostles and asks them: “Do you want to walk away too?” Peter answers: “To whom else can we go?”
“His words function at two levels. On the surface, they express an unwanted humility and helplessness that sometimes beset us all: “I have no alternative! I’m so invested in this relationship that now I have no other options. I’m stuck with this!” That’s a humble place to stand and anyone who has ever given himself or herself over in an authentic commitment will eventually stand on that place, knowing that he or she no longer has another practical choice.
“But those words also express a much deeper quandary, namely, where can I find meaning if I cannot find it in faith in God? All of us have at some point asked ourselves that question. If I didn’t believe in God and had no faith or religion, what would give meaning to my life?”
