I think there have been a few rare souls who really got what Paul was about. In the case of more recent scholars, I was very impressed with the work of Troels Engberg-Pedersen, however I felt that he wasn't fully getting to the heart of things because he was taking a very comparative approach via Stoicism. Timothy Ashworth, on the other hand, seemed to have had deeper insights possibly due to his own transcendental experience. Even so, the latter followed a scholarly approach with his focus on translation and comparison of terminology.
Even earlier, quite a few of us discussed Paul's theology in relation to the work of Gurdjieff. It seemed to me that G, too, had only touched on certain things and there was a distance, a gap, between what he understood and what Paul was truly about. Nevertheless, in Gurdjieff's terms, one could think of Paul's work as a Fourth Way approach.
What really struck me was the realization of how much like what the Cs have exposed in the way of cosmology, anthropology, and theology (including theodicy) Paul's ideas actually were. But, due to time and language barriers, it takes some unpacking to get there, and that's where Ashworth and E-P help so much with their respective studies and insights.
The section of "FPTM" that is of extreme interest in respect of what I have said above is "Markan Epistemology". Note on page 371 where I posit:
1) there are two kingdoms, that of God and that of Satan, which are in deadly opposition to each
other; 2) Jesus has come to rout Satan, ‘plunder his house’ and retrieve those who have spiritual
organs of seeing and hearing; 3) in spite of the fact that Jesus has come to do this, Satan can
still impede the kingdom of God in some ways and one must guard against those wiles if one is
capable. Marcus calls this “the collision of the kingdoms”
This speaks strongly of the STO vs STS positions and that "some love the light and others love the darkness" and "the All blinks neither at the light nor the darkness."
Paul may not have put it in modern terminology, but if one takes care, the "Secret of the Kingdom of God" can be discerned.
Added: One is also reminded of William Blake's poem "Auguries of Innocence" where we find:
Every night and every morn
Some to misery are born.
Every morn and every night
Some are born to sweet delight.
Some are born to sweet delight,
Some are born to endless night.
