Today's WSJ includes a fine column by Rabbi Shmuley Boteach discussing the history of the term "blood libel." Gentle readers will hear the echo of a familiar voice when they read it.
Boteach's false choice on who killed Jesus notwithstanding, we encourage reading of his discussion.
And we repeat here something that our real self often says in person: Christians should stop saying "The Jews killed Jesus." Some did instigate his death; Gentiles carried it out. Some of both groups resisted the move. All kinds of people became his followers after his death and that other thing he did. The main spiritual heroes of Christians are all Jews who didn't stop being Jews when they became Christians.
For those who want to figure out how 1 Thessalonians 2: 14-15 fits into all this, there's a book that we can recommend.
