Like the clouds of the sky, they are here to-day; to-morrow, all swept off and vanished; while Christianity itself, like the heaven above, with its sun, and moon, and uncounted stars, is always over our head, tho the cloud sometimes debars us of the needed light. It must of necessity be the case that our reasonings, and therefore our theological doctrines, are imperfect, and so perishing. It is only gradually that we approach to the true system of nature by observation and reasoning, and work out our philosophy and theology by the toil of the brain. But meantime, if we are faithful, the great truths of mortality and religion, the deep sentiment of love to man and love to God, are perceived intuitively, and by instinct, as it were, tho our theology be imperfect and miserable. The theological notions of Abraham, to take the story as it stands, were exceedingly gross, yet a greater than Abraham has told us, "Abraham desired to see my day, saw it, and was glad." Since these notions are so fleeting, why need we accept the commandment of men as the doctrine of God? This transitoriness of doctrines appears in many instances, of which two may be selected for a more attentive consideration. First, the doctrine respecting the origin and authority of the Old and New Testaments. There has been a time when men were burned for asserting doctrines of natural philosophy which rested on evidence the most incontestable, because those doctrines conflicted with sentences in the Old Testament. Every word of that Jewish record was regarded as miraculously inspired, and therefore as infallibly true. It was believed that the Christian religion itself rested thereon, and must stand or fall with the immaculate Hebrew text. He was deemed no small sinner who found mistakes in the manuscripts. On the authority of the written word man was taught to believe impossible legends, conflicting assertions; to take fiction for fact, a dream for a miraculous revelation of God, an Oriental poem for a grave history of miraculous events, a collection of amatory idyls for a serious discourse "touching the mutual love of Christ and the Church"; they have been taught to accept a picture sketched by some glowing Eastern imagination, never intended to be taken for a reality, as a proof that the infinite God spoke in human words, appeared in the shape of a cloud, a flaming bush, or a man who ate, and drank, and vanished into smoke; that He gave counsels to-day, and the opposite to-morrow; that He violated His own laws, was angry, and was only dissuaded by a mortal man from destroying at once a whole nation,--millions of men who rebelled against their leader in a moment of anguish. Questions in philosophy, questions in the Christian religion, have been settled by an appeal to that book. The inspiration of its authors has been assumed as infallible. Every fact in the early Jewish history has been taken as a type of some analogous fact in Christian history. The most distant events,
