St. Bernard of Clairvaux's Life of St. Malachy of Armagh

The main purpose of this 'Introduction' is to give an account of a movement which changed the whole face of the Irish Church, and to the advancement of which St. Malachy devoted his life. In default of a better word we may call the movement a Reformation, though it might perhaps be more accurately described as an ecclesiastical revolution. Without some knowledge of its aims and progress it is impossible to assign to Malachy his true place in the history of his native country.
