(Matt. vii. 12, Luke vi. 31) is to be found in
the Arab traditions, and many similar points of contact may be
noticed. A man's "neighbour" has ever been, despite the teaching of
Jesus, to the Christian and to the Muhammedan, his co-religionist. The
whole department of Muhammedan ethics has thus been subjected to
strong Christian influence.

Naturally this ecclesiasticism which dominated the whole of life, was
bound to assert itself in state organisation. An abhorrence of the
state, so far as it was independent of religion, a feeling unknown in
the ancient world, pervades both Christianity and Muhammedanism,
Christianity first struggled to secure recognition in the state and
afterwards fought with the state for predominance. Islam and the state
were at first identical: in its spiritual leaders it was soon
separated from the state. Its idea of a divine polity was elaborated
to the smallest details, but remained a theory which never became
practice. Yet this ideal retained such strength that every Muhammedan
usurper was careful to secure his investiture by the Caliph, the
nominal leader of this ecclesiastical state, even if force were
necessary to attain his object. For instance, Saladin was absolutely
independent of the nominal Caliph in Bagdad, but could not feel that
his position was secure until he had obtained his sultan's patent from
the Caliph. Only then did his supremacy rest upon a religious basis
and he was not regarded by popular opinion as a legitimate monarch
until this ceremony had been performed. This theory corresponds with
constitutional ideals essentially Christian. "The tyranny," wrote
Innocent IV to the Emperor Frederick II, "which was once generally
exercised throughout the world, was resigned into the hands of the
Church by Constantine, who then received as an honourable gift from
the proper source that which he had formerly held and exercised
unrighteously." The long struggle between Church and State in this
matter is well known. In this struggle the rising power of Islam had
adopted a similar attitude. The great abhorrence of a secular
"monarchy" in opposition to a religious caliphate, as expressed both
by the dicta of tradition and by the Abbassid historians, was
inspired, in my opinion, by Christian dislike of a divorce between
Church and State. The phenomenon might be explained without reference
to external influence, but if the whole process be considered in
connection, Christian influence seem
