Religion must conform to science

The first and utmost problem is that Bahā’u’llāh, neither regards reason nor science, as a usable tool for recognizing the truth about a religion. Rather, he believes that Baha’ism is the yardstick of truth and anything uttered in it however unscientific and unreasonable that it may be is the absolute truth. He believes that the correctness of peoples’ knowledge and reason must be measured using the words of Bahā’u’llāh, not the other way around:

`Abdu’l-Bahā claims that this principle is new:
Furthermore, He proclaims that religion must be in harmony with science and reason. If it does not conform to science and reconcile with reason, it is superstition. Down to the present day it has been customary for man to accept a religious teaching, even though it was not in accord with human reason and judgment. The harmony of religious belief with reason is a new vista which Bahā’u’llāh has opened for the soul of man.
