Purpose of the Papacy

"It may seem an impertinence on the present writer's part to indite a preface to the work of a brother Bishop; and it would be a still greater one to pretend to introduce the Author of this little book to the reading public, to whom he is so well and so favourably known by a stately array of preceding volumes. Nevertheless Bishop Vaughan has been so insistent on my contributing at least a few introductory lines, that, for old friendship's sake, I can no longer refuse."
