TLDR: At what point does learning about Judaism as a non-Jew cross into appropriation?

I currently attend Quaker meetings.

I have spent the past 8 years of my life curious about Judaism and have dipped in and out of online communities and learning material but have only been to 1 synagogue service irl.

I believe in God and I believe in the importance of living out faith and of ritual (both person to the individual and collective). I don’t believe in Jesus as the Messiah.

I’d like to start attending a local shul regularly (it’s an independent one in the UK that considers itself “traditional”) and I’ve contacted them to ask – it is fine for me to go as a non-Jew

But I’m unsure to what degree I can engage with Jewish tradition, faith and practice without appropriating it. I believe that all faiths have something to say on God and spirituality – I don’t believe any have a monopoly on truth on this – and so would be noticing and bringing in elements into my faith practice. However, from my time in noahide online communities I have also seen that mitzvot only intended for Jews in the Torah have been more widely practised by these individuals, with varying responses from Jews to these “Torah observant” gentiles. I’m looking at learning from the spirit of the law rather than trying to replicate the letter – and am wondering whether something as small is modifying 1 aspect of the law so I am not following it exactly would be sufficient not to be appropriating? I’m thinking things like making sure to do at least 1 thing that violates the Sabbath for example rather than keeping it to the letter. I’m also unsure about prayers – are there certain prayers that are acceptable for non Jews to perform?

Are these questions that I could / would / should raise with the rabbi of the congregation? I don’t really want to be a hassle as a non Jew attendee but I think that guidance might be useful.

Thanks for reading!
