Unless, of course, one already had a PhD in Classics with an emphasis in late Greek philosophy and Patristics (the study of the Church Fathers).
Perhaps the show, as you describe it, might be diverting then, though I've never watched it.
No seriously, the show is a certifiable mindf@#&. The director got death threats as a result of the making that series... which he then actually put into one of the spin-off movies.
The lost memory motif comes from Plato--the memories of each life are wiped out by the soul's drinking from the River Lethe prior to the next reincarnation.
Roger constantly saves Paradigm City, using the power of God, especially from the machinations of its ruler. Don't forget that in the NT the ruler of the world is the Prince of the Powers of the Air--the Devil. This kind of salvation is, of course, the paraclete's--err...Jesus'--primamry function (there's those damn theology books again).
I don't mean to nitpick, but "Powers of the Air" ... if that litterally means dominating the air, then that would hint at Schwarzwald being the devil (or perhaps Alan Gabriel...with the ironic last name). Though I cannot see Schwarzwald as being the devil,
evil yes but not the devil....
Recall, too, that after Jesus' return, he intends to compeltely destroy the world (by then a burnt out battlefield anyway, with all the giant scorpions running around and much else: the oceans turned to poison, the third part of the stars fallen, etc.) before repalcing it with the New Jerusalem.
This here is a contradiction to your "Rog = Jesus" theory.
From Act11 we hear Rosewater say: "Do you know the meaning behind Heaven's Day? ...It's the day God's son was born."
With Alex Rosewater being the only "son" in this series of any significance, and Gordon Rosewater being the absentminded God (the creator of his "cherished tomatoes")... Alex is more the Jesus figure. However, it's only technically... and more likely "anti-Christ" than Christ.
Now to clarify my sensing a contradiction... Alex Rosewater planned to rebuild Paradigm City (the city that his Father had built) by first getting rid of "all you filthy scum". He does this by purposefully destroying Paradigm City. In acts 25 and 26 he constantly mentions reshaping Paradigm in his image. He commisions Beck to capture Dorothy using SCORPION robots. Big Fau is the megadeus of the sea, which has become the death trap for Roger Smith. Big Fau shoots down the stars (stage lights) from the Megadome (aka stage rigging... I just like calling it The Megadome).
Finally... Gordon Rosewater's farm (Garden) is burned to the ground. The destruction of/exile from Eden.
...I think you can see where I'm headed with this.
