The role religious leaders hold within society determines their religious doctrine. The Buddha was a prince, Christ an artisan, Mohammed a merchant and Moses a mandarin.
A prince has the things he needs fall into his lap. An artisan must exchange the artifacts he produces for the things that he needs. A merchant must exchange merchandise at a profit. The mandarin devise civil law.
The Christ, as artisan, looked for a solution to his woes, namely the drudgery of building stools and tables day in, day out. His solution was two-fold. He asked his neighbours to kindly stop requesting these artifacts and be like the birds in the trees and build their own. And he tried to resolve the necessity for raising funds to satisfy his needs by looking to the emancipation of all labour by the downfall of the rich.
Moses, the mandarin, freed his people from slavery to better lord it over them by civil dictates of the state.
Buddha, Siddharta, knew that although his bodily needs were satisfied by no labour of his own, somehow he still was not existentially content. His answer was the suppression of desire in himself.
The Prophet, Mohammed (oops, I feel a fatwah), as bourgeois, knew that the real Adversary were the men labouring in the fields. He devised a means of mentally enslaving them to disarm their rebellion. Hence, Submission to the god of capital.
