Peter Kreeft here, for all his keen articulations which are knowledgeable and insightful, is just another example of how much you should flee Comparative Religion no matter what, and no matter how much the outweighing truth is given to Christianity, for that presentation of outweighing truth will only be an outweighing balance.
Been there, done that.
It's a rum game wherein a "clearer" angle or a pivotal height from which to view Christianity, and from which Christianity is upheld as the truth, somehow becomes a horrible leveling out of the faith to a chilly sort of ground zero.
And people buy into it because it makes them headstrong. They turn the Faith into something they can grasp.
Pope Francis has spoken about ideologies falsifying the Gospel, hasn't he?
Anyways, I was told a story once by one writer who said that a legend says that when the Buddha lay dying, he said to his disciples, "There is one coming in 500 years who is worth more than ten thousand Buddhas."
As with all Aristotles and pre-incarnational pagan prophets, he was halfways or nearly or not quite right, but nearly, or right in a way, and yet in another way, was way, way off the mark and had not the foggiest of the Surprise.
