I'm not really trying to prove anything, just having an interesting discussion hopefully. It is not provable. In fact, both positions could be true. Christ could be the literal son of God in a way we are not and he could be a Zen Master. But, I am citing evidence- the words of Jesus and the words of Zen. Are you denying that Jesus spoke in koans?

Jesus said, "Do not think that I have come to bring peace on earth, I have not come to bring peace, but a sword."

Zen Master Hakuin said, "Should you desire the great tranquility, prepare to sweat beads."

Jesus said, "With man this is impossible, but with God all things are possible."

Zen koan, "If you know the sound of two hands clapping, what is the sound of one hand clapping?"

Jesus said, "To you it has been given to know the secrets of the kingdom of God, but for others they are in parables, so that seeing they may not see, and hearing they may not understand."

Nan Chaun said, "If you approach/seek it, you will most certainly miss it."
