“Traduttore, traditore” (“translator, you traitor!”). Translating ancient texts is hard enough given the complex historical and cultural contexts. When it comes to religious texts, though, the level of complexity grows exponentially, especially given how their contexts widen. On an unrelated note, this always vexes me: > By contrast, the two faiths’ cousin—Christianity I get how one can see a relation between Judaism…
That relation exists but it’s vastly overstated by many people today. Christianity and Talmudic Judaism are both in some sense successors to the old Hebrew religion that the Romans ended by destroying the Temple, but they draw very little from each other. In fact the direct predecessors of today’s rabbis, the Pharisees, are already portrayed in a less than flattering light in the New Testament.
Islam on the other hand positions itself as the successor faith to both Judaism and Christianity. And frankly, nowadays, I’d say that’s the closest relation those two faiths have.
