“One of the fathers of Europe”, who shows us where the continent’s roots are “from which it can be reborn”, and at the same time an example of “detachment from earthly goods, in view of an eternal inheritance”, and of “rejection of compromise” with the powerful. Saint Colombanus, the Irish monk who was the author of a fundamental “Rule”, is the “father of the Church” whose figure and work Benedict XVI illustrated today.  To the 20,000 people present at the general audience, the pope explained in particular the work that the holy monk undertook to re-evangelise a continent that the barbarian invasions had to a great extent led back into paganism.
