Ex umbris et imaginibus in veritatem! - John Henry Newman

Christian! hence learn to do thy part,
And leave the rest to Heaven.

O my brethren, O kind and affectionate hearts, O loving friends, should you know any one whose lot it has been, by writing or by word of mouth, in some degree to help you thus to act; if he has ever told you what you knew about yourselves, or what you did not know; has read to you your wants or feelings, and comforted you by the very reading; has made you feel that there was a higher life than this daily one, and a brighter world than that you see; or encouraged you, or sobered you, or opened a way to the inquiring, or soothed the perplexed; if what he has said or done has ever made you take interest in him, and feel well inclined towards him; remember such a one in time to come, though you hear him not, and pray for him, that in all things he may know God's will, and at all times he may be ready to fulfil it.

[T]he course of ages has fulfilled the prophecy and promise, "Thou art Peter, and upon this rock I will build My Church; and whatsoever thou shalt bind on earth, shall be bound in heaven, and whatsoever thou shalt loose on earth shall be loosed in heaven." That which in substance was possessed by the Nicene Hierarchy, that the Pope claims now.
