Well of course they'd vehemently disagree, they're on a different path and they believe that path goes to a different destination, while in reality necessarily all those path lead to the same destination.
A Hindu might believe they're on a path that leads to reincarnation, a Muslim might believe they're on a path that leads to heaven or hell. At the end of their path though, necessarily something real is going to happen. Whatever their different paths are, that real thing is going to be the same thing for all of us.
The Tao Te Ching might not teach the specifics of what Catholics are speaking of but it might teach what they are trying to achieve in describing their path and what they think lies at the end of it, and how that might be abstracted over many religions in a common attempt at achieving peace, stability and purpose in civilisations.
Logically speaking I do not follow. Why would it be the same? Why could it not be possible that different religious groups would have a different outcome "after living"? It's just as unprovable, no?
Yeah that's true. Though many (most?) religions believe their path/destination is the only true one, so believing there would be different outcomes for different groups would be a new religion those religions would vehemently disagree with. And of course that belief would be itself one of the possible final destinations of all the paths of which only one is true.
The Roman Catholic Church openly claims to be the one true religion, and that all other religions might have elements of the truth, but not the fullness of the Truth. So Catholicism doesn't fit into this framework.
So none of the exclusive claims of any religion to have the full truth are true, but your personal opinion about all of them is fully true? Your arrogance is unbearable.
