By "theistic God", I mean a God who is omnipotent and omnibenevolent and expressed himself through the Tanakh, or at least as powerful as say, Apollo was believed to be in ancient Greek religion.
Different sources seem to be saying different things. Wikipedia says yes, while ReformJudaism.org says not really:
- Wikipedia: "In regard to God, while some voices among the spiritual leadership approached religious and even secular humanism – a tendency that grew increasingly from the mid-20th century, both among clergy and constituents, leading to broader, dimmer definitions of the concept – the movement had always officially maintained a theistic stance, affirming the belief in a personal God."
- https://reformjudaism.org/blog/2018/01/19/do-you-have-believe-god-be-jew: "When people tell me that they don’t believe in God – either because they have seen no empirical evidence that God exists or because they can’t rationally accept the God of the Bible and of the medieval rabbis – I understand completely. I don’t believe in that God either. [...] God is the mystery within us – inside every soul, in the love that inspires generosity and compassion."
- https://reformjudaism.org/practice/ask-rabbi/can-reform-jew-believe-torah-word-god: "In fact, I know of one Reform Rabbi who believes that Torah was revealed at Sinai [...] but that doesn't disqualify him as a Reform Rabbi! We're a big-tent religion, and everyone agreeing on everything isn't the point, and it's never going to happen, anyway. [...] Many Reform Jews have a deep belief in a God that is not literal or theistic, but rather is more mystical or spiritual."
- https://www.timesofisrael.com/9-things-to-know-about-reform-jews/: "About 29 percent of Reform Jews say they believe in God with absolute certainty, compared to 41 percent of Conservatives and 89 percent of Orthodox."
- Note that the article doesn't say how the respondents define God.
By contrast, Reconstructionist Judaism is quite clear that it does not believe in a theistic God. (edit: https://judaism.stackexchange.com/a/20459/19619 says otherwise.)
I'd like recent official statements from organizations representing Reform Judaism, even if it's just that Reform Judaism has no official position on this, and/or a survey of Reform Jews that allows for nuanced perspectives of what God means to them.
Do Jewish people believe in God? is a related question but does not specify Reform Judaism (and I think by default questions on this site are assumed to be about the Orthodox perspective).
