Louis McBride has a good post on the disturbing tendency among some to entertain old heresies. His final paragraph is worth repeating.
“For an increasing number of Christians today to suggest that something is a heresy (even though it was labeled as such over a century ago) is politically incorrect, rude and the height of intolerance. Whereas many of the New Testament authors and first- and second-century church fathers fought hard to protect the church from the devastating effects of heresy nowadays we want to open up a dialogue with them.”
