As Baha’is, we are not to distinguish between any of the Messengers of God, who we call Manifestations of God, because we believe God is One and all his religions were all revealed by the One True God. Each Messenger had a specific purpose and mission that was “pertinent” to the day in which He appeared. We are not to make distinctions between any of the Messengers or elevate one over another.
"Beware, O believers in the Unity of God, lest ye be tempted to make any distinction between any of the Manifestations of His Cause, or to discriminate against the signs that have accompanied and proclaimed their Revelation. This indeed is the true meaning of Divine Unity, if ye be of them that apprehend and believe this truth. Be ye assured, moreover, that the works and acts of each and every one of these Manifestations of God, nay whatever pertaineth unto them, and whatsoever they may manifest in the future, are all ordained by God, and are a reflection of His Will and Purpose. Whoso maketh the slightest possible difference between their persons, their words, their messages, their acts and manners, hath indeed disbelieved in God, hath repudiated His signs, and betrayed the Cause of His Messengers.”
Gleanings From the Writings of Bahá’u’lláh, pp. 59-60
The spiritual verities of all the divinely revealed religions are the same and they are eternal. However, only one message from God is “pertinent” for every age in history because the times change and the needs of humanity change over time. God, the Divine and All-Knowing Physician knows what we need in any given age of history, and He sends a “new” Messenger when we need a “new” message. That message is always different from the previous message, and there will always be another message in the future that is pertinent to future times, because mankind and his world are constantly evolving. So there is no One and Final Truth since Truth is always relative to the times in which it is revealed. Also, we will never know the Ultimate Truth because only God has that Truth.
“No man, however acute his perception, can ever hope to reach the heights which the wisdom and understanding of the Divine Physician have attained. Little wonder, then, if the treatment prescribed by the physician in this day should not be found to be identical with that which he prescribed before. How could it be otherwise when the ills affecting the sufferer necessitate at every stage of his sickness a special remedy?”
Gleanings From the Writings of Bahá’u’lláh, p. 80
“The All-Knowing Physician hath His finger on the pulse of mankind. He perceiveth the disease, and prescribeth, in His unerring wisdom, the remedy. Every age hath its own problem, and every soul its particular aspiration. The remedy the world needeth in its present-day afflictions can never be the same as that which a subsequent age may require. Be anxiously concerned with the needs of the age ye live in, and center your deliberations on its exigencies and requirements.”
