> no one is actually the Buddha
I'm an atheist, but I've studied this, and I think this is a matter of major disagreement in the different schools.
In the west, more contemporary (and often secular) teachers talk about how everyone is a potential Buddha.
There are also close parallels with the more hippie, Christian schools that arose in the 1960s-1970s era (intentional communities) which also taught (quietly I might add), that everyone is a potential Christ.
While this might seem like a trivial point, we do see signs of these teachings arising in the past, from century to century.
These ideas are generally criticized as heretical and repressed because they threaten the hegemonic, institutional nature of religion, which still maintains that the one true interpretation is that there is a single figure (Christ, Buddha, etc) that adherents should aspire to worship, and that they can never equal or match.
The heretical version states the opposite. These adherents believe that Christ and Buddha (assuming for the sake of this argument that they are real, historical figures) did not teach so that they could be worshipped, they taught so that others could become like them.
When you see the religions in this way, then yes, everyone is truly the potential Buddha and the potential Christ, and the vast institutional power of the church disappears, and the roles of priests and clerics vanishes with them.
This kind of change has the effect of emphasizing philosophy over ideology, and places the onus of being a good person and doing good works on the here and now, not on some mythical afterlife or legendary heaven or hell.
