Nevertheless the reality of God-given leadership is extremely repugnant in human experience. Of the five principles of Islamic belief, the Imamate is the most difficult for people to grasp and adhere to. That is because people like to eat from the tree of the knowledge of good and evil. In Genesis two and three the very first story about human beings is of their succumbing to the desire to decide for themselves what is right and wrong, for that is literally what eating from the tree signifies.
People prefer to decide for themselves what is right and wrong rather than relying on the whole chain of divine revelation. The verbal revelation is subject to interpretation and leaves loopholes for personal decisions about right and wrong. Verbal revelation lets you talk yourself into almost anything. Confrontation with a living authority does not. The book of Genesis does not make an overt issue of such authority. It presents the thing as a matter of course.
Noah is one of the greatest examples Muslims refer to in presenting the Imamate. Anyone who followed the verbal revelation meticulously, yet failed to enter the ark, was destroyed along with the sinners. This telling argument summarizes the Bible teaching of the Imamate. There is, however, in the story of Noah a detail much overlooked. How did Noah determine which animals were clean and which were unclean?
Up to that point the dominion of food permitted only fruits, grains and nuts for human consumption. Animals are mentioned only in terms of skins and burnt offerings. Most Christians are unwilling to postulate a verbal revelation of divine legislation. Most people want to relegate the ten commandments to the time of Moses.
Yet even if we presuppose a detailed divine legislation before the time of Noah, there are still always points of practice in determining clean and unclean that require on the spot evaluation. That on the spot evaluation is what most clearly shows Noah to be an Imam or leader by divine authority. There is an even clearer example in the case of Abraham. Some might suggest that the distinction between clean and unclean we find with Noah, goes back only to Moses.
Hardly anyone will want to maintain that lying was forbidden only from the time of Moses. When to hide the truth and when to tell all is precisely a question that verbal revelation can never cover completely. On the spot evaluation is essential.
