How have we learned Christ?

"How have we learned Christ? It ought to be a startling thought, that we may have learned him wrong. That must be far worse than not to have learned him at all: his place is occupied by a false Christ, hard to exorcise! The point is whether we have learned Christ as he taught himself, or as men have taught him who thought they understood, but did not understand him... The Christian religion, throughout its history, has been open to more corrupt representation. Have we learned Christ in false statements and corrupted lessons about him, or have we learned himself?"
