‘Abdu’l-Bahá said:

“…Religion and science are the two wings upon which man’s intelligence can soar into the heights, with which the human soul can progress. It is not possible to fly with one wing alone! Should a man try to fly with the wing of religion alone he would quickly fall into the quagmire of superstition, whilst on the other hand, with the wing of science alone he would also make no progress, but fall into the despairing slough of materialism…”
(Paris Talks by ‘Abdu’l-Bahá, p. 143)

“The third principle or teaching of Bahá’u’lláh is the oneness of religion and science.  Any religious belief which is not conformable with scientific proof and investigation is superstition, for true science is reason and reality, and religion is essentially reality and pure reason; therefore, the two must orrespond. Religious teaching which is at variance with science and reason is human invention and imagination unworthy of acceptance, for the antithesis and opposite of knowledge is superstition born of the ignorance of man. If we say religion is opposed to science, we lack knowledge of either true science or true religion, for both are founded upon the premises and conclusions of reason, and both must bear its test.”
(The Promulgation of Universal Peace, p. 107)

“Religion must conform to science and reason; otherwise it is superstition. God has created man in order that he may perceive the verity of existence and endowed him with mind or reason to discover truth. Therefore, scientific knowledge and religious belief must be conformable to the analysis of this divine faculty in man.”
(The Promulgation of Universal Peace, p. 287)
