In your letter you state that some are perplexed by the question, "Why this God, who is proved to be the God also of the Old Testament, is pleased with new sacrifices after having rejected the ancient ones. For they allege that nothing can be corrected but that which is proved to have been previously not rightly done, or that what has once been done rightly ought not to be altered in the very least: that which has been rightly done, they say, cannot be changed without wrong." ¹ I quote these words from your letter. Were I disposed to give a copious reply to this objection, time would fail me long before I had exhausted the instances in which the processes of nature itself and the works of men undergo changes according to the circumstances of the time, while, at the same time, there is nothing mutable in the plan or principle by which these changes are regulated. Of these I may mention a few, that, stimulated by them, your wakeful observation may run, as it were, from them to many more of the same kind. Does not summer follow winter, the temperature gradually increasing in warmth? Do not night and day in turn succeed each other? How often do our own lives experience changes! Boyhood departing, never to return, gives place to youth; manhood, destined itself to continue only for a season, takes in turn the place of youth; and old age, closing the term of manhood, is itself closed by death. ² All these things are changed, but the plan of Divine Providence which appoints these successive changes is not changed. I suppose, also, that the principles of agriculture are not changed when the farmer appoints a different work to be done in summer from that which he had ordered in winter. He who rises in the morning, after resting by night, is not supposed to have changed the plan of his life. The schoolmaster gives to the adult different tasks from those which he was accustomed to prescribe to the scholar in his boyhoo; his teaching, consistent throughout, changes the instruction when the lesson is changed, without itself being changed.
