In the Name of Allah, the Most Beneficent, the Most Merciful. This is a short introduction to the "original sin" concept in christian theology. What is original sin? Although Christianity emphasizes the inherited original/Adam's sin, this principle cannot be traced back to any prophet. No prophet preached it. All prophets emphasized the individual's responsibility for his own words and deeds, as God’s message is the same in its basics with all the prophets. The doctrine of Original Sin basically boils down to this: Everyone has "inherited" this sinful nature from Adam. This sinful nature is going to make humans sin, or is a causative something back of the will. God is going to condemn everyone to Hell for having this sinful nature. Atonement and reconciliation The word atonement is used in Christian theology to describe what is achieved by the alleged death of Jesus. The word was first used in 1526 to translate the Latin word reconciliatio. In the Revised Standard Version the word reconciliation replaces the word atonement. Atonement (at-one-ment) is the reconciliation of men and women to God through the death of Jesus. But why was reconciliation needed? Christian theology suggests that Everybody carries this original sin of Adam with them which separates them from God, just as Adam and Eve were separated from God when they were cast out of the Garden of Eden. The Atonement is that Jesus paid the penalty for the original and other sins of men by his death on the cross of Calvary, and that salvation cannot be obtained without belief in the saving power of his blood. "There is no single doctrine of the atonement in the New Testament. In fact, perhaps more surprisingly, there is no official Church definition either." (http://www.bbc.co.uk...esusdie_1.shtml) Jesus taught that salvation lies in good deeds and faith, but the church states that salvation and success was achieved through crucifixion. The teachings of he who they believe to be the son of God, are not in line with what present day churches preach, the illogicality and inconsistency of their faith is obvious. Original sin is an Augustine Christian doctrine that says that everyone is born sinful. The root of Christianity is the original sin upon which the crucifixion is justified and used for the benefit of Christians. Like trinity, Jesus never said I would be crucified for Adam's sin nor did he said that children are born sinful. None of these are found in the entire Bible. The concept of Original Sin was explained in depth by St Augustine and formalised as part of Roman Catholic doctrine by the Councils of Trent in the 16th Century. Getting rid of original sin The way a person can 'cleanse' their soul from sin is to accept that Christ's death on the cross atoned for this sin to be baptised. Many Christians who profess to believe in the doctrine of original sin do not know what it teaches. Even more Christians are ignorant of its history and origin.
