Could he only be sanctified, the best candidate might be that good Catholic Marshall McLuhan. Don’t laugh — he was very much a good Catholic. He even won an appointment from the Vatican in 1973.
McLuhan’s truths, like “the media is the massage” (usually misread as “the medium is the message”), still resonate nearly two decades after his death. But my favorite is this one: “Most people are alive in an earlier time, but you must be alive in our own time.”
Interesting too on this page is Isidore’s ideas about choice.
Heresy is from the Greek word meaning “choice”… But we are not permitted to believe whatever we choose, nor to choose whatever someone else has believed. We have the Apostles of God as authorities, who did not… choose what they would believe but faithfully transmitted the teachings of Christ. So, even if an angel from heaven should preach otherwise, he shall be called anathema.
There is some glimmer of truth in this… we have freedom to choose what we believe, but only if we are happy with nonsense, we are forced to choose from the domain of the credible! That does not leave much, probably not even the authorities Isidore looked to.
