Islam and Christianity are the two monotheistic religions fundamentally based on the idea of one God. While they do have similarities such as doing good to others be it through SadaqahJariyah in Islam or giving charity in Christianity as well as having a morality, both are considerably different.
Both these religions are different in terms of who is God, how people should worship, what they should believe, and how they should live life.
Starting from the major difference, pertaining to the nature of God, it must be noted that in Islam Allah is the God – the sole creator of the entire universe – while in Christianity – God is the eternal being that preserves and creates everything. In Islam, Allah is the only one considered worthy of worship, and He has none equal or related to Him in any way. Hence, only submission and worship of Him can get someone in heaven. However, in Christianity, God has a son, Christ who he sent to redeem mankind and only by worshipping Jesus Christ can anyone enter heaven. Islam recognizes that Jesus Christ did indeed exist and he was a prophet but not the son of the living God. Plus, the adherents of Islam – Muslims – believe that Prophet Muhammad (PBUH) is the most superior of all messengers. According to them, Prophet Muhammad is the last messenger of God and he is the one to be followed, not Jesus Christ who was indeed a prophet as well.
One of the most pivotal points in Christianity is the crucifixion of Jesus Christ on the cross. Christians firmly believe that it by shedding his own blood, Jesus Christ performed a precious act and an ultimate sacrifice that cleansed everything. Muslims, on the other hand, believe that Jesus Christ was not in fact crucified on the cross and that Allah saved His messenger from such a death.
Moving onto the main scripture of both religions, Islam has the Quran as the ultimate source of guidance and direct message from Allah while Christians have the New Testament, which they also refer to as the Injil. Muslims are of the opinion that the Holy Book of Christians, Injil has been corrupted and therefore is unreliable. They also believe that the Quran is both a continuation of Allah’s message in Injil and correction of the errors that Christians added in the New Testament. Hence, according to Muslims Quran is the only true source of guidance. Again, Christians donors believe this, and they consider both the Old and New Testament to be the infallible word of God.
Last but not least, Muslims do not believe in the concept of salvation as Christian does. For instance, Muslims think that every individual should pay for his or her own sin, and it wasn’t necessary for Jesus Christ to bear the brunt of the sins of others. On the other hand, Christians believe that individuals cannot atone for their own sins, and it is only the grace of God that can be the source of salvation.
Without a doubt, both Christianity and Islam are fundamentally different religions as is evident from the number of adherents of both these religions around the globe and the extent to which it is believed that one threatens the other. However, it must be kept in mind that there are similarities as well. For instance, good deeds such as sponsor an orphan or answering Syria Urgent Appeal to the plight of people in need are appreciated in both of them.
