Do all religions worship the same God?

Judaism has always been less interested in tidy theological declarations than in the hard work of living faithfully. So when Jewish thinkers encounter this question, they tend to resist both the easy answer ("yes, we all worship the one God") and the dismissive one ("no, everyone else has it wrong"). The tradition holds something more careful and, frankly, more interesting than either position.

At the heart of Jewish theology is the absolute oneness of God, expressed most concisely in the Shema. God is not a being among other beings, not a personality who can be straightforwardly described, but the ground of all existence. Medieval thinkers, most notably Maimonides, pressed this so far as to say that even positive attributes cannot truly be applied to God. To say God is "wise" or "good" in the same way a human is wise or good is already a kind of distortion. This matters for the question at hand, because it means that what any tradition says about God, including Judaism itself, is at best an approximation of something that finally exceeds all description.

From this vantage point, the question shifts. Rather than asking whether different religions are worshipping the "correct" God, Jewish thought tends to ask something more practical: what is the quality of the relationship, and what does that worship actually produce in the lives of those practising it? The Talmudic concept of the Noahide laws reflects a belief that the one God has a relationship with all of humanity, not just the Jewish people. Non-Jews are not seen as excluded from that relationship simply by not being Jewish. A righteous person from any nation, the tradition holds, has a place in the world to come. This is not a small thing. It is a structural acknowledgement that God's presence and concern is not the private property of one community.

Where Judaism draws a firm line is around idolatry, and this is where the question gets genuinely complicated. Not all religious practice is treated as equivalent. Worship that involves images understood to be gods in themselves, or beliefs that fragment divine unity into competing powers, is something the tradition treats with real seriousness. Historically this has shaped how different Jewish authorities viewed Christianity and Islam. Many authorities, including significant medieval and modern figures, came to regard Islam as straightforwardly monotheistic and therefore without the idolatry problem. Christianity presented a harder case, particularly around the Trinity and the veneration of images, and Jewish legal discussions about this stretch across centuries and remain alive today. There is no single Jewish ruling on the matter, which is itself revealing.

If you are wrestling with this question personally, perhaps because someone you love follows a different path, or because you are trying to make sense of your own faith alongside the faiths of the wider world, Judaism offers something genuinely useful. It does not require you to conclude that everyone is ultimately doing the same thing, because that would flatten real and meaningful differences. But it also does not require you to conclude that everyone outside your tradition is cut off from the divine. The God of Jewish understanding is not a tribal deity. The rabbis teach that Adam was created alone so that no person could say "my ancestor is greater than yours." The one God is the God of all people, even where the understanding of that God differs, sometimes profoundly.

Living with that tension is not a weakness in the tradition. It is one of its strengths. Judaism asks you to take your own relationship with God seriously, to inhabit it with rigour and love, and to hold open the possibility that the mystery you are orienting your life towards is also, in ways you may not fully understand, what others are reaching towards in their own way. That is not the same as saying it does not matter what anyone believes. It is something more honest than that.
