On attending Shabbos dinners

Evan Myers is being strugglesessioned because he won't attend Shabbos (=Sabbath, for KJV).

First up, if a Jew is going to complain about a Gentile not attending a Jewish ritual; said Jew must then explain why they cannot sit in upon an Orthodox Sunday Mass. "Idolatry!", the Jew will respond. Which is fair enough! Jews as Jews do not, can not, recognise Jesus bar Miriam as Christ. In fact, some edgelords among them consider him a momzer boiling submerged in a nasty substance in Hell. And you know, they're right: per CS Lewis himself, if Jesus was wrong, that's the afterlife he deserves. I can accept that those who do not believe what we believe are not going to want to partake in the rituals in which we partake. (We at least agree upon the Saracens.)

How can a German participate in a ritual based in an ancestral exodus from a land they never knew? The German might not always have been German (geneticists are now saying the culture came from the Bottenviken) but such assuredly were never Canaani. And this assumes Evan is not an Ó Meidhir, nor a Cymraeg - they've never not been Irish or Welsh, respectively. The ritual is simply not theirs.

Thomas Aquinas Summa Theologica I-II, q.103, a.4 agreed; this entered the Canon Law too (1917) #1258. I recall the Letters of James of Edessa preaching against attendance as well; although not in our confessional tradition, Jacob's statements of praxis represent the Late Antique baseline of transconfessional relations.

I will here disclose that I could accept an invitation to a Sabbath. But... I am a good part Jewish. Saint Paul has granted dispensation to my kinfolk who are Christian. So I cannot speak for Myers.

Overall, Myers' decision lies within his own conscience. It should be assumed to be in good faith.
