Fundamentalism is the new '-ism' for the church to fight

The Catholic church is well-known for its opposition to many important "-isms" over the years: It has railed against secularism, materialism, communism, and modernism with vigor and determination. Now it appears Pope Francis has decided to argue against an "-ism" of a different sort.

For more than a year now, Francis has repeatedly returned to the issue of religious fundamentalism and has condemned it, whether Christian, Muslim or Jewish fundamentalism.
