I'm not sure there is any glory in banning someone (regardless of the specific definition of the word) for telling the truth. In either case it's a shameful episode.
Also, now that I think about it, in Linnaeus' time in many countries the Catholic Church was still a quasi-governmental institution. If it wasn't explicitly part of the government, in many cases it had a lot of power over the government. So a ruling by the Church often had as much coercive power as a law passed by the King.
So I doubt that a "banning" by the Church meant soley that Linnaeus would be barred from taking communion, or some similarly narrowly defined proscription.
