People who go down the path of trying to explain the Trinity, and especially the incarnation, are bound to get burned. It’s like trying to explain the Xzehgeis on Saiubislgds-9.
BTW-I watched MacArthur a while back on TV where he was interviewed along with several other “Christians” including a high ranking priest. When asked if Christ was the only way to heaven everyone but MacArthur pussy-foot around the real answer. MacArthur was the only one who said that Christ was the only way to heaven.
You may quibble over some of MacArthur’s erroneous views which he later has recanted. One may recall that the great Augustine found himself in a similar situation, even to the point of having to recall his books to be burned. But MacArthur sticks up for the gospel time and again. He is an honorable man.
