True religion

"An essential principle of Bahá’u’lláh’s teaching is that religion must be the cause of unity and love amongst men; that it is the supreme effulgence of Divinity, the stimulus of life, the source of honor and productive of eternal existence. Religion is not intended to arouse enmity and hatred nor to become the source of tyranny and injustice. Should it prove to be the cause of hostility, discord and the alienation of mankind, assuredly the absence of religion would be preferable. Religious teachings are like a course of treatment having for its purpose the cure and healing of mankind. If the only outcome of a course of treatment should be mere diagnosis and fruitless discussion of symptoms, it would be better to abandon and abolish it. In this sense the absence of religion would be at least some progress toward unity.

Furthermore, religion must conform to reason and be in accord with the conclusions of science. For religion, reason and science are realities; therefore, these three, being realities, must conform and be reconciled. A question or principle which is religious in its nature must be sanctioned by science. Science must declare it to be valid, and reason must confirm it in order that it may inspire confidence. If religious teaching, however, be at variance with science and reason, it is unquestionably superstition. The Lord of mankind has bestowed upon us the faculty of reason whereby we may discern the realities of things. How then can man rightfully accept any proposition which is not in conformity with the processes of reason and the principles of science? Assuredly such a course cannot inspire man with confidence and real belief. "
