Today is the feast of St. John Henry Newman, Doctor of the Church. From one of his sermons:
My Brethren, there are those who imagine that, when we use great words of the Church, invest her with heavenly privileges, and apply to her the evangelical promises, we speak merely of some external and political structure. They think we mean to spend our devotion upon a human cause, and that we toil for an object of human ambition. They think that we should acknowledge, if cross-examined, that our ultimate purpose was the success of persons and parties, to whom we were bound in honour, or by interest, or by gratitude; and that, if we looked to objects above the world or beyond the grave, we did so with very secondary aims and faint perceptions. They fancy, as the largest concession of their liberality, that we are working from the desire, generous, but still human, of the praise of earthly superiors, and that, after all, in some way or other, we are living on the breath, and basking in the smile, of man. But the text, and the train of thought which I have been pursuing, remind us of the true view of the matter, were we ever likely to forget it. The Church is a collection of souls, brought together in one by God's secret grace, though that grace comes to them through visible instruments, and unites them to a visible hierarchy. What is seen, is not the whole of the Church, but the visible part of it. When we say that Christ loves His Church, we mean that He loves, nothing of earthly nature, but the fruit of His own grace;—the varied fruits of His grace in innumerable hearts, viewed as brought together in unity of faith and love and obedience, of sacraments, and doctrine, and order, and worship. The object which He contemplates, which He loves in the Church, is not human nature simply, but human nature illuminated and renovated by His own supernatural power....
