Don Marco has this:
The Slammer of Heretics
Saint Nicholas is celebrated for his role at the First Council of Nicaea. According to legend, he became so incensed upon hearing the views of Arius that he rushed over to the hapless heretic and gave him a mighty blow on his ears, sending him sprawling. That, of course, was when the testosterone of Catholic bishops was proportionate to their orthodoxy.
There is a popular saying in Russia: If God should leave us, do not worry will still have St Nicholas. We seem to have lost any real memory of St Nicholas, so over laid with legend is any actual history. Like many of the great saints his popularity lies not so much in what he did but in what does. He continues to pray and work miracles, and show God's love for his people.
