In contrast many years ago when I visited a nearby Reform Judaism synagogue on a Sabbath day (merely to see what it was like), during the service the Rabbi urged me (a non-Jewish stranger to him), to partake of the bread of wine. Since I was already an atheistic Secular Humanist by then, I refused to do so (because I didn't want to give the impression of participating in worship).
At another time when I was already an atheistic Secular Humanist, I was attending a service of a nearby congregation of Humanistic Judaism. During part of the service the bread and small paper (or plastic) cups of wine (which had secular humanistic meanings in the service) were passed around to everyone present (including to young children), including to me, and I partook of them. Each person received their own bread and their own small cup of wine (unless they didn't want the wine; I think there was an option for water instead of wine).
During the service emblems were passed around at multiple times, each serving received had a somewhat different meaning (I think each pertained to a different blessing and a season of the year or each month of the year, but I don't recall for certain). But I didn't like drinking the wine because I could feel the alcohol effecting me adversely (I could feel it starting to intoxicate me) from the multiple small (possibly one ounce) servings of wine, thus at some point I stopped accepting more servings of wine (which was permissible to do).
By the way, years ago I stopped fully identifying as a Humanist (since I don't agree with all of the precepts of Humanism), though I still identify as an atheist. I now prefer to identify as a scientific/philosophical (or even metaphysical) naturalist instead of as a Humanist.
