Thought this might be an interesting topic.
Just re-read one of my favorite DC Comics Presents stories the other day that was in a recent Showcase trade that had Superman fighting with the Spectre where God talks to Superman at the end of the story.
This was back when Supes could do pretty much anything. In this story he's trying to rescue his cousin when he's stopped by the Spectre as he's about to cross a barrier that he's not supposed to nor is he allowed to. All he had needed to do was just ask. Nice ending to a good 3 part story that introduced Mongul and besides the Spectre also had Supes teaming up with the Martian Manhunter & Supergirl. I originally bought it because I had never read a story with Martian Manhunter at the time. The story drew me in and I was blown away that God actually spoke to Clark towards the end.
I remember buying this issue because at the time it was a big damn deal that Jim Starlin was drawing something for DC
Those were some good issues, and Starlin's time at DC was pretty brief from roughly 1978-1981. DC COMICS PRESENTS 26-29, and 36-37. SUPERBOY/LEGION 239 and 250-251. A Batman story in DETECTIVE COMICS 481-482. And a few scattered covers for these books and HOUSE OF MYSTERY, JLA, BATMAN FAMILY and others.
His time at DC was because of a clash with Jim Shooter, and he went to DC only because of that. And went back when Marvel started its creator-owned line, where Starlin could deal with Archie Goodwin at Marvel, without having to deal directly with Jim Shooter. From this came Starlin's "Metamorphosis Odyssey" in EPIC ILLUSTRATED 1-9 (1980-1981).
And DEATH OF CAPTAIN MARVEL (late 1981) and DREADSTAR (Summer 1982) graphic novels.
And the DREADSTAR continuing series beginning in late 1982 and continuing (by both Marvel/Epic and First Comics) for the remainder of the 1980's.
The graphic novel that occurs between "Metamorphosis Odyssey" and Marvel's DREADSTAR graphic novel is THE PRICE graphic novel, published in Oct 1981 by Eclipse.
Starlin also did "Darklon the Mystic" for Warren in EERIE magazine 76 (Aug 1976), 79 (Nov 1976), 80 (Jan 1977), 84 (May 1977) and 100 (April 1979). Collected later by pacific Comics in 1983 in a one-shot DARKLON THE MYSTIC 1.
I met Jim Starlin at a Miami show in February of 1993, and he let on that the consistent themes of death, God and the afterlife that ran through the above works, as well as his 1970's CAPTAIN MARVEL and WARLOCK runs, and also stories in STAR REACH 1 (1974) and ECLIPSE magazine 1 (1981), was brought on by the impact of his father's death.
The two stories that for me most directly answer the portrayals of God in the above listed works are Starlin's stories in EPIC ILLUSTRATED 6 (where Aknaton summons his culture's God to seek advice and approval of his genocidal plans).
And THE PRICE graphic novel (also reprinted in color as DREADSTAR ANNUAL 1) on the protagonist mystic/priest Syzygy Darklock's sacrifice that was more about personal revenge, but was also about personal sacrifice in the name of pre-ordained destiny, to a pantheon of gods, and creatures of god-like power. With an interesting surface appearance of clothing and religious hierarchy similar to that of the Catholic church.
There are at least two directions this topic could explore.
1) Portrayals of the Judeo/Christian God (Yahweh/Jehovah, Father, Son and Holy Ghost)
2) gods of other cultures (such as Muslim, Hindu, Buddhist and other concepts of God)
and
3) possibly purely allegorical or fictitious portrayals of God, such as Crom in the Conan stories.
