And one final point. The ancient Israelites thought that the sacred could be contaminated by the impure, and so sought to retain ritual purity for their lives. Christianity teaches the exact opposite; when the sacred comes into contact with the profane, the profane is sanctified. In our faith, Christ clearly demonstrates that anything which is truly sacred cannot be defiled. If it could, that would make sin more powerful than God, which is nonsense.
Islam appears to return to the Israelite attitude to holiness; it is a retrograde step from what Christ himself teaches us, in other words. In Islam, as in Judaism, sin has the power to undo what God himself does. In our faith, nothing has this much power. You can take a Holy Bible, and do what you like with it; it remains Holy. That which God has done, man cannot undo.
