Edouard Louis Montet (1856-1934) was a famous French scholar and professor of theology and professor of oriental languages at the University of Geneva. He has analysed the rationalistic character of the Islamic creed, and the advantage it reaps due to it in its missionary efforts, has to say the following about Islam and its teachings:
“Islam is a religion that is essentially rationalistic in the widest sense of this term considered etymologically and historically. The definition of rationalism as a system that bases religious beliefs on principles furnished by the reason, applies to it exactly.
It is true that Muhammad, who was an enthusiast and possessed, too, the ardour of faith and the fire of conviction, that precious quality he transmitted to so many of his disciples,—brought forward his reform as a revelation: but this kind of revelation is only one form of exposition and his (Muhammad’s) religion has all the marks of a collection of doctrines founded on the data of reason.
To believers, the Muhammadan creed is summed up in belief in the unity of God and in the mission of His Prophet, and to ourselves who coldly analyse his doctrines, to belief in God and a future life; these two dogmas, the minimum of religious belief, statements that to the religious man rest on the firm basis of reason, sum up the whole doctrinal teaching of the Quran.
The simplicity and the clearness of this teaching are certainly among the most obvious forces at work in the religion and the missionary activity of Islam”.
Professor Montet says further:
“In spite of the rich development, in every sense of the term, of the teachings of the Prophet, the Qur’an has invariably kept its place as the fundamental starting-point, and the dogma of the unity of God has always been proclaimed therein with a grandeur, a majesty, an invariable purity and with a note of sure conviction, which it is hard to find surpassed outside the pale of Islam.
This fidelity to the fundamental dogma of the religion, the elemental simplicity of the formula in which it is enunciated, the proof that it gains from the fervid conviction of the missionaries who propagate it, are so many causes to explain the success of Muhammadan missionary efforts.
A creed so precise, so stripped of all theological complexities and consequently so accessible to the ordinary understanding, might be expected to possess and does indeed possess a marvellous power of winning its way into the consciences of men.”1
