Willem Balke's Calvin and the Anabaptist Radicals relates an anecdote of interest on page 197. Apparently a Baptistic purveyor of tracts was arrested, and out of desperation in his defense accused Calvin of greed. It's not clear exactly how he expected this charge to be received, but the response was that everyone started laughing. Apparently, the town had recently offered Calvin an increase in his stipend, which he had refused on the strongest terms -- even swearing that he would refuse to preach anymore if they gave it to him!
The only other person I've ever read who accused Calvin of greed was a Church of Christ member on a web forum. It may not be a coincidence; I wonder if the unbiblical practices of some CoC / Mormon / etc. groups in not providing their pastors with official financial support stems from some of these early roots.
While the ultimate disposition of the case is hard to approve of, that part of it was interesting, and a very good testimony of Calvin in contrast to the Roman church of his day.
