Heresy Emerges from the Swamp of Bad Theology or Over Emphasized Truth

I think it might be demonstrated that almost every heresy that has afflicted the church through the years has arisen from believing about God things that are not true, or from overemphasizing certain true things so as to obscure other things equally true.  To magnify any attribute to the exclusion of another is to head straight for one of the dismal swamps of theology; and yet we are all constantly tempted to do just that.
