In answer to the video "Muslims' Worst anti-Christian Polemics: Corruption of the New Testament"
Besides failing on a historical level for lack of external evidence, the crucifixion story as depicted in the Greek Christian writings fails on an internal, theological level. According to habakkuk1, the everlasting God "will never die". The Quran equally states
25:58"And rely upon the Ever-Living who does not die, and exalt [Allah] with His praise".
Humans have a dual nature, the body and the spirit. Lets call that human being John. John has thus a human body and a spiritual essence. John gets nailed on a cross and dies. His body expires while his spirit transitions to the hereafter. To say that John did not die on the cross because his spiritual essence survived would be false. Similarily God, according to the trinity doctrine has both a human body and a spiritual essence. God gets nailed on a cross and dies. His human nature expires while his spiritual essence transitions. To say that God did not die because his spiritual essence survived would then be as false as in John's case.
Yet even from a materialistic standpoint, death is the end of life. In religion, death ends life in the present world and begins life in the hereafter. How does the ever-living, eternal God cease living in anyway shape or form? Assuming God did not die when he was crucified. This would then undermine the notion of atoning sacrifice. Death and loss is what validates the atonement. If God did not die, losing nothing in the process, then what did He sacrifice on the cross? Habakkuk1 is a general statement. It excludes death in any way. It doesnt say God's spirit cannot die while his body can. This is an example of what an explicit statement, closed to any misinterpretations, is. It is what is referred to in religious terminology, a firm verse, or as the Quran says, muhkam. A religion based on solid explicit tenets, does not seek ambiguous verses and try to derive isolated meanings upon which to build an entire belief system. Whenever confronted to ambiguous verses, that are open to several contradicting interpretations, we consider the context, the words used and cross reference them with other similar verses. More importantly, whatever the conclusion we come up with, the interpretation may never contradict the explicit, firm, decisive verses. But that is not how Pauline christianity works. In order to circumvent the statement that God "will never die" and make it fit the belief of divine sacrifice, it is said that this sacrificing Christian god didnt really die. Assuming God did not die when he was crucified. This would then undermine the notion of atoning sacrifice. Death and loss is what validates the atonement. If God did not die, losing nothing in the process, then what did He sacrifice on the cross?
Further, why would God go as far as killing his son (or self) to prove his trustworthiness and capacity to truly forgive, and how is it a proof of love? Only an unjust, deluded criminal, unworthy to be the judge of mankind would think that murder is a proof of love. Why would anyone trust an entity, divine or else, willing to commit suicide (or even worse, kill its own progeny) to prove its love? One would instead try helping such entity out of its delusion. One would not want in anyway to be associated with such demonstration of "passionate love".
God, since times immemorial has been demonstrating His love through the prophets, sending promises of mercy and forgiveness before that mythological Greek drama was invented. Believers have always known and trusted this fact attested in scriptures over and over again, which God made contingent on repentance and obedience to His commandements. Nobody thought God would fail His promise, or was incapable of forgiving the servants that wholeheartedly turn to Him. The Quran treats such hopelessness in God as a mark of disbelief
39:53-4"Say, "O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allah. Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful. And return [in repentance] to your Lord and submit to Him before the punishment comes upon you; then you will not be helped"
15:56"And who despairs of the mercy of his Lord except for those astray?".
That attribute of mercy is in fact the only one described in the Quran as "written upon" God 6:12,54. Christians on the other hand do not expect God to be merciful, to the point they need him to prove his capacity to forgive by murdering his own self/son. Furthermore, a judge that forgives someone because of the actions of another, Jesus' sacrifice in this case, isnt a merciful judge. Forgiveness wasnt triggered by the mercy of the judge, rather by the price paid by another. So although Christians do believe in their God's absolute mercy, in reality their concept of the divine is far removed from it. The profound difference in relation to that theological aspect between Islam and Christianity goes back to the story of the garden. While in the Quran, the story ends with hope and forgiveness, in Christianity it is misconstrued in a way the Jews who read the same scriptures before them, vehemently dispute.
In the Quran Adam is sent away from the garden with the message that whenever guidance is recognized and acted upon, then mankind "shall not go astray nor be unhappy". There is therefore in the Quranic account of creation no place for unconditional, senseless and indiscriminate condemnation. On the contrary, the incident is concluded with forgiveness and spiritual guidance. The Christian belief on the other hand is that there was no forgiveness, sin became ingrained in human nature and transmitted to Adam's progeny. On top of that, God, instead of sending the solution to that "problem" in the shape of Christ's atoning death, establishes a long line of prophethood and laws to be followed. This divinely decreed deceptive crooked system was bound to fail in the face of human depravity, for several thousands of years, until the issue of salvation was finally resolved with the crucifixion. This theology appeals to people who have despaired of life, themselves and God. It is toxic, as it crushes the person's self esteem, making him yield to dark thoughts of hopelessness in oneself, and it is satanic as it discourages the building of a relationship with a merciless, unloving God. Hope is therefore found elsewhere, neither in God nor man, but in an intercessor that fixes the defects of both so as to reconcile them. He is a sinless man and a merciful, loving God, both in one since the divine cancels sinfulness and the human cancels mercilessness and unlovingness. His divine nature makes this man capable of perfect deeds thus pleasing God and restoring His (God's) hope in man, while his human nature makes this God capable of dying, and through this self-sacrifice, capable of showing love and mercy, thus pleasing man and restoring his hope in God.
That is why the Quran quotes Jesus himself, emphatically denying the man-made, unscriptural notion of sin atonement as understood by those that deified him
5:72"and the messiah said; ...serve Allah, my Lord and your Lord. Surely whoever associates with Him, then Allah has forbidden to him the garden, and his abode is the Fire; and there shall be no helpers for the unjust".
In this short statement, Jesus nullifies everything Trinitarian Christianity stands for, the idea of a divine entity other than God being the means by which one's eternal felicity and freedom from sins depends.
In another place, Jesus, instead of taking upon himself the sins of mankind, denies even the sins of his own followers that began deifying him. He washes his hands from their deviations and submits to God's justice, leaving the entire prerogative of salvation in God's hands
5:116-118"If You should chastise them, then surely they are Your servants; and if You Should forgive them, then surely You are the Mighty, the Wise".
In the monotheistic faith, the prominence of God's attribute of mercy does not mean it comes freely. It is earned, through concrete, repeated, steadfast actions proving one's sincere penitent resolve. This however is only beneficial in relation to God's rights. But if a sin includes infringing on other people's rights then the divine law has declared it an injustice to deprive a victim of its due rights. In that case it is upon the victim to either benevolently forgive and turn away, or demand restitution for the harm done. No human sacrifice was needed before Jesus for people to known and trust in those things which the prophets said. It is ironic that in the book of Isaiah, the one most appealed to and distorted to prove the abhorrent notion of human sacrifice as the only prerequisite for sin atonement, God says
Isa55"my ways are different from yours".
This comes right after the reassuring statement that God is near and hearer of prayers so
"Let the wicked leave their way of life and change their way of thinking. Let them turn to the LORD, our God; He is merciful and quick to forgive".
God's nature is contrary to human's who need and ask their debt to be settled in case of foul play. There are no debts between men and God, He doesnt lose anything from people transgressing His commands neither does He gain from their worship. His glory remains unchanged in both cases. That is why he does not need to be propitiated.
For His mercy to be released, the sinner does not need to act in relation to God but to his own self, through repentance and mending of ways. This deed is one that has no effect on God but on the sinner, cleansing his own soul. It is as a result of the person taking action to cleanse his self, that God releases His mercy, blotting out the sin completely and forgives Isa43. This is the main, among many other avenues for forgiveness which the HB gives besides blood atonement.
The concept of atoning sacrifice is nowhere to be found in Jesus' words anyway. He nowhere speaks of his own death as an atonement for sin. He is instead depicted as talking of his life as being a ransom Mk10:45, but in a clear context of dedication and humility. He is dedicating his life for the sake of others, like all selfless people should. It is Paul who connected these words with expiation for sins in 1Tim2. This spin caused intense debates and disagreements throughout the ages among all branches of Christianity; ranging from the notion of Jesus' life being the ransom paid back to Satan who held humanity in hostage, to the idea that God the Father was the one to receive the payment, and many other nuances in between. The inherent problems to every proposition, the contradictions each of them create with various Christian doctrines such as God literally ransoming himself to himself, is what led the Roman Catholic Church to describe the ransom theory as a "mystery of universal redemption".
