Just looking back on this thread suggests to me that when Thomas Merton spoke of the Person as the next great issue in inter-faith dialogue, he was not wrong.
Again, the subject of Incarnation and what exactly is meant.
William Blake, in "Auguries of Innocence", wrote...
We are led to Believe a Lie
When we see not Thro the Eye
Which was Born in a Night to perish in a Night
When the Soul Slept in Beams of Light
God Appears & God is Light
To those poor Souls who dwell in Night
But does a Human Form Display
To those who Dwell in Realms of day
Do we need to believe in THE Incarnation to recognise what William Blake is saying?
But just "the Human Form"? What about all other forms?
Here is Alan Watts, seeking to reject the cry of "Pantheism"...
The moment I name it, it is no longer God; it is man, tree, green, black, red, soft, hard, long, short, atom, universe. One would readily agree with any theologian who deplores pantheism that these denizens of the world of verbiage and convention, these sundry “things” conceived as fixed and distinct entities, are not God. If you ask me to show you God, I will point to the sun, or a tree, or a worm. But if you say, “You mean, then, that God is the sun, the tree, the worm, and all other things?”—I shall have to say that you have missed the point entirely.
So there we are. Seeking clarity of mind, much to reflect upon and consider, always recognising that (maybe) “Words can be communicative only between those who share similar experiences.”
