I will claim ignorance, but I am not aware of who Mr. Davies is. Can you enlighten me?
Mr. Davies is the former President of the Una Voce Federation, and one of the foremost scholars associated with promotion of traditional Catholicism.
He was a first and foremost a historian, writing extensively about the Catholic Church in England during the protestant revolution, and much about the Catholic Church in the face of the current revolution and crisis.
Nothing I could write about him could do him any justice. I saw him speak during his battle with cancer (which he described as a "minor health condition", so as not to have those in the crowd feeling sorry for him), and the man was simply amazing. He will be missed.
Michael Davies was president of Una Voce International (an international federation of associations, founded in 1966 in Rome, that now includes national associations in 17 nations on every continent. It is dedicated to ensuring that the Roman Mass codified by St. Pius V is maintained as one of the forms of eucharistic worship which are honored in universal liturgical life, and to restoring the use of Latin, Gregorian Chant, and sacred polyphony in Catholic liturgy.), and is the author of many books on Catholic history and liturgy.
