The origin of expiatory sacrifices can not, we think, be explained except on the principle of a primitive revelation and a positive appointment of God. They can not be understood except as a divinely-appointed symbolism, in which there is exhibited a confession of personal guilt and desert of punishment; an intimation and a hope that God will be propitious and merciful; and a typical promise and prophecy of a future Redeemer from sin, who shall "put away sin by the sacrifice of himself." This sacred rite was instituted in connection with the _protevangelium_ given to our first parents; it was diffused among the nations by tradition, and has been kept alive as a general, and, indeed, almost universal observance, by that deep sense of sin, and consciousness of guilt, and personal urgency of the need of a reconciliation, which are so clearly displayed in Grecian mythology. The legitimate inference we find ourselves entitled to draw from the words of Paul, when fairly interpreted in the light of the past religious history of the world, is, that the Athenians were a religious people; that is, _they were, however unknowing, believers in and worshippers of the One Supreme God_. CHAPTER IV. THE RELIGION OF THE ATHENIANS: ITS MYTHOLOGICAL AND SYMBOLICAL ASPECTS. "That there is one Supreme Deity, both philosophers and poets, and even the vulgar worshippers of the gods themselves frequently acknowledge; which because the assertors of gods well understood, they affirm these gods of theirs to preside over the several parts of the world, yet so that there is only one chief governor. Whence it follows, that all their other gods can be no other than ministers and officers which one greatest God, who is omnipotent, hath variously appointed, and constituted so as to serve his command."--LACTANTIUS. The conclusion reached in the previous chapter that the Athenians were believers in and worshippers of the One Supreme God, has been challenged with some considerable show of reason and force, on the ground that they were _Polytheists_ and _Idolaters_. An objection which presents itself so immediately on the very face of the sacred narrative, and which is sustained by the unanimous voice of history, is entitled to the fullest consideration. And as the interests of truth are infinitely more precious than the maintenance of any theory, however plausible, we are constrained to accord to this objection the fullest weight, and give to it the most impartial consideration. We can not do otherwise than at once admit that the Athenians were _Polytheists_--they worshipped "many gods" besides "the unknown God." It is equally true that they were _Idolaters_--they worshipped images or statues of the gods, which images were also, by an easy metonymy, called "gods."
