Theological differences between Christian denominations play an important role, with Catholics in Ireland almost 80% less likely to support Israel than Protestants, the survey found.
“Even after we control for politics, for various religious beliefs, for demographic factors like race and income, we still find that Catholics in all countries are less supportive of Israel and are more likely to endorse antisemitic tropes than Protestants,” Bumin noted.
The research also identified a significant generational divide, with younger Irish respondents being substantially less supportive of Israel than older generations. Under-30 respondents in Ireland are 87% less likely to support Israel than those 65 or older, according to the report.
A unique phenomenon in Ireland is that many antisemitic attitudes in Ireland appear to originate within churches themselves, Bumin noted. Beliefs such as supersessionism (the idea that God’s covenant with the Jewish people has ended) and blaming Jews for the crucifixion of Jesus are “far more widespread in the Irish community than they are in America,” he said.
Pastors and religious leaders could help fight antisemitism by playing down those aspects of belief while emphasizing the connection between the Abrahamic covenant, Bumin suggested.
