Another of his questions: “In the Mahábád and Zoroastrian religions it is said: ’Our faith and religion is superior to every other. The other Prophets and the religions they have instituted are true, but they occupy different stations before God, even as, in the court of a king, there is a gradation of ranks from the prime minister to the common soldier. Whosoever wisheth, let him keep the precepts of his religion.’ Nor do they impose upon any soul…”

Regarding their statement that “our faith and religion is superior to every other”, by this is meant such Prophets as have appeared before them. Viewed from one perspective these holy Souls are one: the first among them is the same as the last, and the last is the same as the first. All have proceeded from God, unto Him have they summoned all men, and unto Him have they returned.
