Now if it’s true that our dear Chabadniks are not seeking to evangelize both Jew and Gentile, putting them head to head with the core faith mission of Christianity, then someone please say so. But from the description above it didn’t look like it.
Anyhow, it matters to a crazy Christian like me when someone is given a false gospel. Knowledgeable Christians will take a light hand with respect to Jewish people. They will fulfill the mission of showing the gospel in an attractive manner.
However when we got preachers out there preaching against us then this is spiritual war!
And my personal thrust here? Same as Paul’s: I bear them witness that they have a zeal for God, but not in accordance with knowledge. I would not be surprised to see the Chabad approach dissolve into a series of sarcastic remarks when faced with serious, thoughtful Christian theological assertions. But as for us crazy Christians, we still say God bless them (and as modern Israel has made manifest, we “pay” God bless them too).
Chabad is a group that actually carries out the Jewish mission to bring non-Jews out of false religions like chrstianity and to the Noachide Laws. They're not the only group that does this but they're one of the biggest and best known.
