Blessed John Henry Newman on the Modern and Ancient Church

From the twelfth lecture in his post-conversion series "Certain Difficulties Felt by Anglicans in Catholic Teaching"

"No other form of Christianity but this present Catholic Communion, has a pretence to resemble, even in the faintest shadow, the Christianity of Antiquity, viewed as a living religion on the stage of the world. This has ever attached me to such works as Fleury's Church History; because, whatever may be its incidental defects or mistakes, it brings before the reader so vividly the Church of the Fathers, as a fact and a reality, instead of speculating, after the manner of most histories, on the principles, or of making views upon the facts, or cataloguing the heresies, rites, or writers, of those ancient times. You may make ten thousand extracts from the Fathers, and not get deeper into the state of their times than the paper you write upon; to imbibe into the intellect the Ancient Church as a fact, is either to be a Catholic or an infidel."
