Few issues show more clearly show the error of the supposed infallble authority of the Roman Catholic Church (or the Eastern Orthodox Church!) than that of icon veneration. That may sound strange, but both Catholic and Eastern Orthodox theologies claim that the findings of the Second Council of Nicea (787 AD) were infallible. And at this council, the veneration of icons is not just affirmed, but all who reject it are put under a supposedly infallible 'anathema'! This is no small matter.
