Moreover, while it is certain that developments of Revelation proceeded all through the Old Dispensation down to the very end of our Lord's ministry, on the other hand, if we turn our attention to the beginnings of Apostolical teaching after His ascension, we shall find ourselves unable to fix an historical point at which the growth of doctrine ceased, and the rule of faith was once for all settled. Not on the day of Pentecost, for St. Peter had still to learn at Joppa that he was to baptize Cornelius; not at Joppa and Cæsarea, for St. Paul had to write his Epistles; not on the death of the last Apostle, for St. Ignatius had to establish the doctrine of Episcopacy; not then, nor for centuries after, for the Canon of the New Testament was still undetermined. Not in the Creed, which is no collection of definitions, but a summary of certain _credenda_, an incomplete summary, and, like the Lord's Prayer or the Decalogue, a mere sample of divine truths, especially of the more elementary. No one doctrine can be named which starts complete at first, and gains nothing afterwards from the investigations of faith and the attacks of heresy. The Church went forth from the old world in haste, as the Israelites from Egypt "with their dough before it was leavened, their kneading troughs being bound up in their clothes upon their shoulders." 13. Further, the political developments contained in the historical parts of Scripture are as striking as the prophetical and the doctrinal. Can any history wear a more human appearance than that of the rise and growth of the chosen people to whom I have just referred? What had been determined in the counsels of the Lord of heaven and earth from the beginning, what was immutable, what was announced to Moses in the burning bush, is afterwards represented as the growth of an idea under successive emergencies. The Divine Voice in the bush had announced the Exodus of the children of Israel from Egypt and their entrance into Canaan; and added, as a token of the certainty of His purpose, "When thou hast brought forth the people out of Egypt, ye shall serve God upon this mountain." Now this sacrifice or festival, which was but incidental and secondary in the great deliverance, is for a while the ultimate scope of the demands which Moses makes upon Pharaoh. "Thou shalt come, thou and the elders of Israel unto the King of Egypt, and ye shall say unto him, The Lord God of the Hebrews hath met with us, and now let us go, we beseech thee, three days' journey into the wilderness, that we may sacrifice to the Lord our God." It had been added that Pharaoh would first refuse their request, but that after miracles he would let them go altogether, nay with "jewels of silver and gold, and raiment."
