Christianity as a specific doctrine was slain with Jesus, suddenly and utterly. He was hardly cold in his grave, or high in his heaven (as you please), before the apostles dragged the tradition of him down to the level of the thing it has remained ever since.
We are never without a pilot. When we know not how to steer, and dare not hoist a sail, we can drift. The current knows the way, though we do not. The ship of heaven guides itself, and will not accept a wooden rudder.
As to those other things which we hold on the authority, not of Scripture, but of tradition, and which are observed throughout the whole world, it may be understood that they are held as approved and instituted either by the apostles themselves, or by plenary Councils, whose authority in the Church is most useful, e.g. the annual commemoration, by special solemnities, of the Lord's passion, resurrection, and ascension, and of the descent of the Holy Spirit from heaven, and whatever else is in like manner observed by the whole Church wherever it has been established.
Nor aught availed him now to have built in heaven high towers; nor did he scrape by all his engines, but was headlong sent with his industrious crew to build in hell.
Truly, it is a blessing and not a blasphemy when I teach that "above all things there stands the heaven of chance, the heaven of innocence, the heaven of accident, the heaven of wantonness".
What Heaven has conferred is called The Nature; an accordance with this nature is called The Path of duty; the regulation of this path is called Instruction. The path may not be left for an instant. If it could be left, it would not be the path.
We thought of life by analogy with a journey, a pilgrimage, which had a serious purpose at the end, and the thing was to get to that end, success or whatever it is, maybe heaven after you’re dead. But we missed the point the whole way along. It was a musical thing and you were supposed to sing or to dance while the music was being played.
CLEOPATRA: If it be love indeed, tell me how much. ANTONY: There's beggary in the love that can be reckoned. CLEOPATRA: I'll set a bourne how far to be belov'd. ANTONY: Then must thou needs find out new heaven, new earth.
