The greatness of Christopher Columbus

In what does the greatness of Christopher Columbus consist?

We say not that he was unmoved by perfectly honourable aspirations after knowledge, and deserving well of human society; nor did he despise glory, which is a most engrossing ideal to great souls; nor did he altogether scorn a hope of advantages to himself; but to him far before all these human considerations was the consideration of his ancient faith, which questionless dowered him with strength of mind and will, and often strengthened and consoled him in the midst of the greatest difficulties. This view and aim is known to have possessed his mind above all; namely, to open a way for the Gospel over new lands and seas.

And this is precisely why Columbus is portrayed as one of history's greatest monsters in today's government schools.
