The Answering Islam Organization for instance puts forward the argument that “Christianity and Islam share much common ground. Both trace their roots to Abraham. Both believe in prophecy, Gods messengers (apostles), revelation, scripture, the resurrection of dead, and the centrality of religious community.” It is also interesting to note that regarding a doctrine like salvation, the two religions have both contrasts and similarities.
The comparison and contraction of salvation as it pertains to the two religions thus Christianity and Islam shall be viewed from three major perspectives. These are the origin of sin, the way to salvation and the consequences of salvation. A detailed discussion of the three perspectives would give a pre-salvation conceptualization, salvation conceptualization and post-salvation conceptualization.
On the issue of origin of sin, which eventually brings to the need for salvation, both Christianity and Islam believe that the first family (Adam and Eve) sinned against God. The difference with the two religions however is the fact that whereas in Christianity is it believed that the sin of Adam and Eve lives on and makes all humankind sinful, thus the need for salvation, Islam believes that the sin of Adam and Eve were forgiven and that generations thereafter bears no condemnation of the first sin. The Answering Islam Organization terms this situation as the originality of sin. According to the organization, “Christianity teaches that the effects of original sin have corrupted the world and the human beings who exist in it.” “In Islam, however, there is no such a thing as original sin. The Quran does indeed state that Adam and Eve sinned, but according to Islamic belief, they repented and were fully forgiven so that their sin had no repercussions for the rest of human race.”
