US more liberal then Europe

Perhaps the Papacy is fervently anti-Nazi during the war, and does its best to help Jews escape, and this sparks a Catholic revival after the war?

The individual priests and and religious orders did so, whether or not the Papacy said they could or told them not to. If not the fear of communism and the Germans invading there could be outbreaks of violence over the invasions of the Basque country, France, Belgium, Poland, Austria, and the Nazi violence against religion and attempts to centralize it into two small groups under their own aegis. That and the attempts to remove the Old Testament. A good divergence may be the parish birth records across Europe. The priests would forge conversion records and baptismal documents for people's parents and grandparents so that the children would be not considered Jewish. Though the Germans would have went for them anyways. Maybe part of Poland get's their free elections, a socialist state has a revolution supporting Church in Eastern Europe, and liberals and charity organizations are driven out of Europe. Which is what the Franquists and Falangists thought of the Red Cross.
