According to Tabari, the restrictive allusion to "some of that . . .", etc., bears on the realm of faith and morals alone, since it was not a part of Jesus' mission to deal with problems of his people's worldly life. This observation coincides with the image of Jesus forthcoming from the (admittedly fragmentary) description of his teachings available to us in the Synoptic Gospels.
I.e., with divine revelation.
True wisdom consists in understanding the unity of the Divine purpose and the Unity of the Divine Personality. The man Jesus came to reconcile the jarring sects in Israel, and his true teaching was just the same as that which was expounded in a wider form by Islam. He did not claim to be God: why should not the Christians follow the doctrine of Unity rather than what has become their ancestral and traditional custom?
