So let's imagine that for some reason both Christianity and Paganism die out in Early Medieval Europe, and a new religion, with some relation to Manichaeism and Gnosticism comes to be dominant in Europe after the 3rd Century CE.
In this religion, there is a whole Priestly caste called the "Elect" who hold ceremonies which Catholics would distantly recognize as "Masses" in a church, which a lower caste of people called the "Believers" attend to worship God.
There is no institution akin to Catholicism's celibacy, so members of the Elect simply descend from previous Elect families.
The Elect are promised eternal life after death, and the Believers are promised nothing, just the vague hope that they get to live for another day, before they cease to exist after death.
A conversation that could happen between an Elect priest, and a Believer commoner:
Believer: "So, you, as a member of the Elect adhere to the religion, and as such, God will give you life after death, a way to exist after this material shell of yours gives up."
Priest: "Yes."
B: "And I, as a Commoner will cease to exist after I die."
P: "Yes."
B: "Then why should I attend daily Masses, worship God, and pay taxes to you and other members of the Elect?"
P: "You little piece of shit, have you ever wondered why you ever get to get up every morning and live another day? Why your wife and children can survive? Imagine that you don't attend Mass. Next day, a beam on the roof of your house could snap while you are standing below it and cause your nasty death. You could contract Leprosy. Your male member could shrivel up and fall off, when you are preparing to mate with your wife. The wolf, or a robber could take away your children. Have these happened yet? No? Well these didn't happen yet because as of yet you have faithfully attended Mass and paid taxes to the Church. Imagine what would happen if you didn't. Leprosy is a nasty death, and impotence is a nasty way to live, especially with a wife."
Would a religion like this be possible to become widespread in Europe? What would be the implications of it in future centuries?
