What is the American religion? Most Americans are pluralistic, relativistic, humanistic. . . and they believe man can save himself. That applies to 46% of pentecostals, 41% of evangelicals, and 70% of Roman Catholics. There doesn’t seem to be much difference anymore between evangelicals and Catholics. There used to be a 100% gap, now its 29%. For most Americans, truth doesn’t matter anymore, because Americans are PCR.
