I recently made a brachah on a mandarin. An acquaintance, who's not Jewish, responded enthusiastically to hearing the name of G-d that begins with "Ad...", and proceeded to wax poetic on it, mentioning it a few times.
He wasn't necessarily being irreverent, but he did mention the name a few times, something which I've learned is forbidden for a Jew to do casually - the most casual permitted context being, "while learning to pronounce it".
Does a non-Jew risk damaging their soul by pronouncing shemot kodashim that are only not pronounced in informal contexts by way of chumra, like a Jew does?
Or am I perhaps overestimating the severity of them doing so?
The best I could come up with, was to tell him to please just stick to only thinking the name, not pronouncing it and instead saying "HaShem" when referring in speech to any specific shem kodesh. But I didn't give a reason so it is unlikely to "stick".
(And yes, the suggestion to use "Aloshi" and "Adoshi" is helpful, but is one step beyond my question.)
