One of the objections laid against orthodox Christianity is the concept of a loving father sending his innocent son to suffer and die for the guilt of others. Men make every effort to deconstruct the plain reading of scripture and restate the narrative in a way that removes the scandal of the cross. Why? Such a sacrifice is abhorrent. Justice demands that the guilty should pay for his or her own transgressions. For someone or something to die as a substitute for wrongdoing runs counter to our thinking. Why should a living thing shed its blood for my behalf? In the following from his work against pagans, Arnobius takes up a similar argument that bears some investigation.
And can any man persuade himself that the gods become mild as they are exhilarated by pleasures, that they long for sensual enjoyment, and, like some base creatures, are affected by agreeable sensations, and charmed and tickled for the moment by a pleasantness which soon passes away?
But the gods should be free from both passions, if we would have them to be everlasting, and freed from the weakness of mortals. Moreover, every pleasure is, as it were, a kind of flattery of the body, and is addressed to the five well-known senses; but if the gods above feel it, they must partake also of those bodies through which there is a way to the senses, and a door by which to receive pleasures. Lastly, what pleasure is it to take delight in the slaughter of harmless creatures, to have the ears ringing often with their piteous bellowings, to see rivers of blood, the life fleeing away with the blood, and the secret parts having been laid open, not only the intestines to protrude with the excrements, but also the heart still bounding with the life left in it, and the trembling, palpitating veins in the viscera? We half-savage men, nay rather,—to say with more candor what it is truer and more candid to say,—we savages, whom unhappy necessity and bad habit have trained to take these as food, are sometimes moved with pity for them; we ourselves accuse and condemn ourselves when the thing is seen and looked into thoroughly, because, neglecting the law which is binding on men, we have broken through the bonds which naturally united us at the beginning.
Will any one believe that the gods, who are kind, beneficent, gentle, are delighted and filled with joy by the slaughter of cattle, if ever they fall and expire pitiably before their altars? And there is no cause, then, for pleasure in sacrifices, as we see, nor is there a reason why they should be offered, since there is no pleasure afforded by them; and if perchance there is some, it has been shown that it cannot in any way belong to the gods.
The Case against the Pagans, Book VII, cap. 4
A cursory reading has the writer castigating the practice of bloody sacrifice as unnecessary since any divine being would not be given to pleasure by the slaughter of these beasts. He argues strongly that deity is impassible and that these offerings are not compatible with that high character. That begs the question: Does the God Arnobius confesses desire such sacrifices? And what of the sacrifice of Jesus on the cross?
Why sacrifices?
The first step is to establish why someone would feel the need to offer a sacrifice. There is within mankind an understanding that a gap exists between a person who is a corporeal entity and the incorporeal deity. A gap exists either because of shortcomings or just the inadequacy of ability in communicating from one level of existence to the other. In either case, something must bridge the chasm in order for interaction to occur.
The Bible tells us that there was originally fellowship between God and man—as much closeness in a relationship as is possible between the Creator and his creation. This was ruined by man's disobedience, and the sin resulted in a chasm (Gen 3:17-24). While no animal sacrifice was required, they were given from earliest times. The earliest recorded came from Abel who gave of the flock which was accepted (Gen 4:4).
While the early sacrifices were useful in approaching God, man still lacked basic knowledge of how short he came in his attempts and what was needed to ease the situation. Through Moses was communicated the Lord's holy character and his expectation of a holy people. Because of the sin nature within every one of his people, God also gave stipulations for the sacrifices needed to atone for those sins, because
the life of the flesh is in the blood, and I have given it for you on the altar to make atonement for your souls, for it is the blood that makes atonement by the life. (Lev 17:11)
A life was required in order to deal with sin. Since the Lord so valued human life (see Gen 1:26; 2:7) above animal life, the blood of specific livestock was offered in a prescribed manner as a substitute for the individual or nation.
Something Better
God has said in his word that there is something he desires above sacrifice.
Has the LORD as great delight in burnt offerings and sacrifices,
as in obeying the voice of the LORD?
Behold, to obey is better than sacrifice,
and to listen than the fat of rams. (1 Sam 15:22)
Sacrifice and offering you have not desired,
but you have given me an open ear.
Burnt offering and sin offering
you have not required.
Then I said, "Behold, I have come;
in the scroll of the book it is written of me:
I desire to do your will, O my God;
your law is within my heart." (Psa 40:6-8)
What to me is the multitude of your sacrifices?
says the LORD;
I have had enough of burnt offerings of rams
and the fat of well-fed beasts;
I do not delight in the blood of bulls,
or of lambs, or of goats.
. . .
Wash yourselves; make yourselves clean;
remove the evil of your deeds from before my eyes;
cease to do evil, learn to do good;
seek justice, correct oppression;
bring justice to the fatherless,
plead the widow’s cause. (Isa 1:11, 16-17)
The sacrificial system was installed because of sin, but what God wanted more than anything else was obedience. Continual sacrifices were a measure to cover sin for a time but never completely dealt with the issue. Something more was required to deal with all sin forever.
Ultimate Answer
Because man had sinned, a man had to deal with the problem, but nobody was sufficient to the task. To deal with the shortcoming, God himself stepped into this world as fully man, yet remaining fully God. As man, he could represent us to pay the debt of his own precious blood. As God, the sacrifice was of infinite worth and power to cover all sin. None more were required (Heb 7:27; 9:12; 9:26; 10:10). The bloody sacrifice that was not needed by man in the beginning or wanted by God, but given by necessity, is now completed for all time, so that if we but trust in Jesus' finished work on the cross, we might walk in newness of life as new creations in Christ.
