The “Revelation of the Manifestation of God is the standard for all knowledge”

While it may often be the part of wisdom to approach individuals or an audience from a standpoint of current knowledge, it should never be overlooked that the Revelation of the Manifestation of God is the standard for all knowledge, and scientific statements and theories, no matter how close they may come to the eternal principles proclaimed by God's Messenger, are in their very nature ephemeral and limited. Likewise, attempting to make the Bahá'í Faith relevant to modern society is to incur the grave risk of compromising the fundamental verities of our Faith in an effort to make it conform to current theories and practices.
