FF7 has both Kabbalistic nods, Gnostic nods and Christian nods, though all of the nods towards Christianity are through a Gnostic lens, particularly the Sethian strain of Gnosticism. I wont go into more so as not to spoil anything, but I think I actually may be able to go into more detail and clarity about this than most of the writing about it I've seen online. Im sure there are a few youtube videos that may give me a run for my money though.
