A trinitarian God, such as Christianity’s, not compatible with the God of Judaism.
That I fully agree with.
You are flat out wrong to say Jesus isn’t God according to Christians.
Again, you're missing the point as "the Mystery of the Trinity" is what's used, and if the teaching of the RCC is that Jesus is fully God in every
literal sense, then it would no longer be a "Mystery". Think Aristotle and Plato, and then think of the word "essence" that Plato used in this context.
But I find it quite the definition of chutzpah for you to tell a Jew what is or isn’t Jewish.
LOL! If you think for one minute that there's unanimity when it comes to trying to "define" haShem, then it is you who has that as a problem. And even if I was a Christian, when you pull the arrogant crap that you did above, it certainly doesn't help your cause any as it comes off like "Us Jews know it all and you Gentiles haven't a clue".
Maybe it's best not to strut around in such a condescending manner like you did above, but then you support Trump-- no surprise. Also, it wouldn't be a bad idea if you actually know at least a bit about the person you're insulting-- think "halacha".
