He was not a liar, his words were spirit, just as he said. And "the spiritualizing gig"...is God's gig. Some/many reject him. Apparently, you are one who does.
You bet! I reject the Hellenization of scripture interpretation that was developed by Origen and solidified by Augustine and supported by John Calvin. Allegorical interpretation is not God's gig. It is man made. And it led from Origen thru Augustine thru Luther thru Calvin straight to the gas chambers of Auchschwitz.
And it waters down the pure, simple Gospel of Yeshua.
When one uses a allegorical "spiritualizing" approach to scripture, one can pull off a lot of nonsense. This is an extreme example, but quite apropos.... grabbing a scripture that says "Judas hanged himself" and grabbing another that says "Go and do Likewise" and trying to make a doctrine of that.
The only principled hermeneutic approach is that of ... "when the plain sense of scripture makes sense, then seek no other sense lest one end up with nonsense".
But so many want to do the gnostic thing of trying to find the deeper meaning. Origen really botched that up with stuff like the Parable of the Good Samaritan.
The traveler was really Adam
Jerusalem became Paradise
Jericho became the world
The Robbers became hostile influences
Priest and Levite became the Law and the Prophets
The Good Samaritan became Jesus
The Inn became the Church
The 2 Denari became the knowledge of the Father and the Son
The Inn Keeper became the Angels that watch over the Church.
