Dude I'll probably come back to this thread and add some more thoughts ... but I wanted to respond quickly and just toss a few cents in there:
* Fringe is RIFE with religious elements. All throughout. And purposefully so. It's almost hard to separate the exploration of the "unknown" from spirituality, because the god that society is coming to know more and more on a daily level is the "god of the gaps" ... the god that exists hidden in the cracks of what we do NOT know, whilst we think what we know we have figured out and is missing a god alltogether, apart from laws of physics
That having been said, I think pointing out individual moments where spiritual themes are used in Fringe would take up more than a single thread could hold lol. The direct references, however .... those are interesting and allude to what I assume the writers are ultimately going to tell us in the finale of the series.
* And having just said that lol .... and reading your post, I'm assuming the writers are basically going to either attempt to prove or disprove the existence of god in the series. Directly. Now .... what they will end up with as being the "apex force" in the universe? That is something I could easily guess at .... but it sounds almost too cheezy to even mention. lol Needless to say, I think overall that the fans are going to be pleased with Fringe as a whole ... but it's final message is going to be less than spectacular to most people. It will be thought provoking to some, and anti-climatctic to others
It will basically be like opening Abram's mystery box and having him tell you what the emptiness inside of it means
* So ... I think the concept of Mystery as god already exists in Abram's productions and projects. I'm pretty sure you're getting close to one of the ultimate "points" of Fringe by bringing it up in this thread
And we see, in the characters, that each one of them reacts differently to that Mystery. Some find Mystery to be sacred .... something which is so valuable that it needs to remain hidden and unspoken of within their hearts and minds. Others mock it. Others think it's a call to arms.
Others think it is something to be dissected .... sometimes to find the benefit of it, other times out of malice and disillusionment with it.
And some .... merely embrace it and let it flow through them and they it ... becoming an extension of it. Heroes of it. The embodiment and representation of it.
Children of it
