...the Torah that God hath confirmed consists of the exact words that streamed forth at the bidding of God from the tongue of Him Who conversed with Him (Moses).

Bahá’u’lláh, from a previously untranslated Tablet, Extracts From The Bahá’í Writings And From Letters Of The Guardian And The Universal House Of Justice On The Old And New Testaments

A star has the same radiance if it shines from the East or from the West. Be free from prejudice, so will you love the Sun of Truth from whatsoever point in the horizon it may arise! You will realize that if the Divine light of truth shone in Jesus Christ it also shone in Moses and in Buddha. The earnest seeker will arrive at this truth.

‘Abdu’l-Bahá, Paris Talks, p. 137

A student of the modern methods of the higher criticism asked ‘Abdu’l-Bahá if he would do well to continue in the church with which he had been associated all his life, and whose language was full of meaning to him. ‘Abdu’l-Bahá answered: "You must not dissociate yourself from it. Know this;  98  the Kingdom of God is not in any Society; some seekers go through many Societies as a traveller goes through many cities till he reach his destination. If you belong to a Society already do not forsake your brothers. You can be a Bahá’í-Christian, a Bahá’í-Freemason, a Bahá’í-Jew, a Bahá’í-Muhammadan. The number nine contains eight, and seven, and all the other numbers, and does not deny any of them. Do not distress or deny anyone by saying 'He is not a Bahá’í!' He will be known by his deeds.

Amongst the great prophets was His Holiness Abraham who, being an iconoclast and a herald of the oneness of God, was banished by the people from his native land.

Blessed souls whether Moses, Jesus, Zoroaster, Krishna, Buddha, Confucius, or Muhammad were the cause of the illumination of the world of humanity. How can we deny such irrefutable proof? How can we be blind to such light?

‘Abdu’l-Bahá, From a Tablet - translated from the Persian

During the years when the darkness of heedlessness was most intense in the Orient and the people were so submerged in imitations that nations were thirsting for the blood of each other, considering each other as contaminated and refusing to associate -- at such a time as this Bahá’u’lláh appeared. He arose in the Orient, uprooting the very foundations of imitations, and brought the dawn of the light of reality. Through Him various nations became united because all desired reality. Inasmuch as they investigated reality in religion, they found that all men are the servants of God, the posterity of Adam, children of one household and that the foundations of all the Prophets are one. For inasmuch as the teachings of the Prophets are reality, Their foundations are one. The enmity and strife of nations, therefore, are due to religious imitations and not to the reality which underlies the teachings of the Prophets. Through Bahá’u’lláh the nations and peoples grew to understand and comprehend this. Therefore, hearts became united, and lives were cemented together. After centuries of hatred and bitterness the Christian, Jew, Zoroastrian, Muslim and Buddhist met in fellowship, all of them in the utmost love and unity. They became welded and cemented because they had perceived reality.
