By contrast...
By contrast, the traditions vary on how they relate to the Sabbath, Judaism observing Saturday, Christianity Sunday, and Islam Friday. By way of experiment I began to think how the Scriptures align themselves with the beliefs and practices of the various traditions. There might well be more features supporting Judaism in the Qur'an than mere reference to Saturday observance, and on the other hand, more features supporting Islam in the Bible than special recognition of Friday.
Since Muslims generally do not know the Bible well, there is every reason to believe that they might be mistaken when they think the Bible supports Christianity. In sum, one question seems never to have been answered: how do Islamic belief and practice compare to the texts of Judaism and Christianity, that is, to the Bible? I first came to the conclusion that the Bible might reflect Islamic features in unexpected ways through a reading of the Sermon on the Mount in Matthew 5-7.
A closer look at this text will reveal how the Bible can express Islamic values even on a structural level. This passage contains the texts which the greatest numbers of Christians know by heart. Some Christian sects, notably those who have descended from the Anabaptists, seem to base the core of their doctrine on this passage alone. The Sermon on the Mount is beloved by Christian and non-Christian alike. The nonreligious person in Christian societies often appeals to its words.
It is said that Gandhi based his practice of nonviolent resistance on it. Since this is indisputably one of the most important texts of Christianity, we can only wonder how well it supports the basic beliefs of Christianity. Some of the most important beliefs of Christianity are these three: Christians believe that God is one God eternally existing in three persons, God the Father, God the Son, and God the Holy Spirit.
Christians believe that the man Jesus is also in one and the same person at one and the same time completely and wholly God Almighty, one and equal with the Father. Finally, Christians believe that salvation and correspondingly forgiveness of sins depend on the atoning sacrifice for sin made by Jesus in his death on the cross. By comparison, the well-known five pillars of Islamic practice are: testifying that there is no god but God; prayer, alms, fasting, and Pilgrimage.
The whole Sermon on the Mount implies time and again that there is only one being who is God, the one Jesus calls `Our Father'.
