Jewish Converts to Catholicism and Jewish-Catholic Reconciliation

I've recently migrated this blog, and the older posts might not yet be satisfactorily cleaned up. Apologies for the temporary mess.

From Nicholas J. Healy’s review of John Connelly, From Enemy to Brother: The Revolution in Catholic Teaching on the Jews, 1933–1965 (Harvard University Press, 2012):

Connelly’s extensive research uncovered a surprising fact. “From the 1840s until 1965, virtually every activist and thinker who worked for Catholic-Jewish reconciliation was not originally Catholic. Most were born Jewish. Without converts, the Catholic Church would not have found a new language to speak to the Jews after the Holocaust.” … Confronted by a racist ideology that had made deep inroads in Catholic thinking in Germany and Austria, these converts discovered through bitter struggle that it was necessary to unconver and heal a deeply rooted contempt for the Jewish people.
