Reading I feel there are three questions asked with the main question:
** Do I believe in hell?
** Is hell here now in this life I have presence with? If so, then what of others for 'Life' as a whole?
** If there is hell is it only after death?
Firstly, answering the last first a resounding 'No' while may be an esoteric answer. That can lend to long discussions. For me it just doesn't seem to fulfill common sense even when reading the scriptures IMO.
The first part of the second question I acknowledge as being metaphorical / allegorical. I feel it speaks of the human condition - mine, and its pathway with some 60 years of experience. I reflect upon Dante's Inferno with its allegorical theme. That was a reading requirement for a class many years ago. I have not read the other two of the trilogy - Divine Comedy, (Purgatory and Paradise). Perhaps, I should?!?
The second part of that question? I really dun'no . . . but, sure seems so today with the broad stroke of the brush. Especially with a big picture view of the world today. Patient smaller brush strokes with care seem to develop a picture of greater beauty. Seems it takes a bit of time to develop the master piece.
Finally, the first . . . most notably is perhaps, but willing to listen. I ponder the second question with its parts. Why can be asked. Because my personal belief system, today, has been founded more on Thomatic thinking with Thesis / Antithesis with many dialogues. I have a lean of it being a synthesis.
