Yeah I like that idea in modern Christianity too, that Hell is just a secular place. Not full of torture, but forever apart from God. Thus awful in the sense that being with God would be infinitely better... But no actual "lake of fire" and such. It's a very reasonable idea, and I think the world might be a better place if the editors of the Bible had believed in it.
Speaking of heresies, I've been reading up on a very interesting one: Catharism! Some of you might know it as "That Crusader Kings 2 heresy that allows female priests" but it's a lot more than that. It was the first appearance of several protestant ideas. They rejected idolatry and the excesses of the Catholic church, practiced voluntary rather than infant baptism, and believed in eventual salvation for all. They were kinda like Quakers in that they refused to kill or swear oaths, strictly following the New Testament.
http://www.cathar.info/cathar_legacy.htm#protestantThey also believed in reincarnation, even into animals, based on your conduct in life! Interesting connection to eastern religions there. They're explanation was that Satan, god of the world, trapped divine souls in mortal bodies. Hell is essentially secular life on Earth, and death is no escape. Fortunately Jesus showed us a way to end the cycle through willing spiritual baptism. It was also kinda like Catholic last rites, though. It was most commonly done for people about to die, inviting a piece of the holy spirit to live in the person and defy Satan's claim on the soul.
Then there were people who chose the baptism earlier, or unexpectedly survived. These "perfects" were like monks:
When a believer underwent the Consolamentum, his or her life changed for ever. After this rite they were members of the Elect. From now on they would lead the life of an ascetic. They were to be completely chaste, and were not permitted even to touch members of the opposite sex. They were not permitted to tell a lie, swear an oath, nor kill any living creature. They would have to undertake frequent fasts, including three 40 day fasts each year.
For those who expected to die within hours this had less significance than for those who undertook the rite without the expectation of imminent death. They lived simple, peaceful, devotional, chaste lives of poverty, often travelling on foot in pairs like the disciples, preaching and working in simple trades like weaving to earn their living. To their followers the Elect were living saints. Touched by the Holy Spirit, they were God's ambassadors in an alien world. The contrast with bejewelled, warmongering, sybaritic, indolent, lascivious Churchmen living on forcibly extorted tithes was difficult for the slowest peasant to miss.
Kinda like if nuns and monks were in charge of the church. And women were allowed to do this too - the faith was apparently popular among women for treating them completely equally.
Here's where they go farther than later protestant faiths: They explain the New Testament vs Old Testament contradiction. They explain why God is an abominable, arbitrary tyrant in the Old Testament, then suddenly does everything he can to save humanity. They explain why the world is wicked, and spirituality is good.
They kiiinda say that the God of the Old Testament, creator of the world is Satan. Having lost the rebellion in heaven, he rules over the material plane instead. Human souls are actually angels he's trapped in "tunics of flesh" to corrupt to his will.
i think it makes sense
