The harmony of religion and science is fundamental and one of the most important factors in fostering peace and tranquility within human society, enabling both material and spiritual progress and aiding in the advancement of civilization. Bahá'u'lláh explains that religion and science are in agreement and harmony, emphasizing that religious truths and scientific facts cannot be in conflict; instead, they are complementary aspects of a single reality. Both religion and science are vital components in the ongoing development of humanity and its progression into an era of comprehensive progress and prosperity across all aspects of life.
Religion serves as the primary source of morality and virtues, offering essential guidance for humanity's quest for spiritual perfection. Science, by contrast, provides the tools through which human intellect explores and makes discoveries, enabling individuals to unravel the mysteries of nature and learn how to apply its laws to enhance and elevate their lives. Together, religion and science function as the two wings by which human understanding can realize its highest potential; one wing alone is insufficient. It is through the harmonious combination of both that humanity achieves material well-being, prosperity, and spiritual advancement.
Religion and science together constitute two complementary aspects of the system of knowledge that propels human civilization forward.
Material civilization is like unto the lamp, while spiritual civilization is the light in that lamp. If the material and spiritual civilization become united, then we will have the light and the lamp together, and the outcome will be perfect.
