I posted this earlier in the thread:
(1) The idea that Jesus is physically or literally the Son of God is derived from the "Son of God" designation that appears throughout the Gospels but also in other New and Old Testament texts.
(2) It is a designation that highlights the Uniqueness and Greatness of Jesus when compared to the rest of humanity.
(3) However other religions may also have different designations such as Muhammad being the seal of the prophets or Baha'u'llah being the Glory of God. These different designations may serve a similar purpose to highlight the Uniqueness of a particular Man who Manifests God's Greatness with a Revelation that transforms communities, traditions, and morals.
(4) There is an underlying unity in all the Great Prophets or Manifestations of God.
"Christ ratified and proclaimed the foundation of the law of Moses. Muhammad and all the prophets have revoiced that same foundation of reality. Therefore the purposes and accomplishments of the divine messengers have been one and the same. . . ."
"The mission of the prophets, the revelation of the holy books, the manifestation of the heavenly teachers and the purpose of divine philosophy all center in the training of the human realities so that they may become clear and pure as mirrors and reflect the light and love of the Sun of Reality."
"The function and purpose of a shepherd is to gather and not disperse his flock. The prophets of God have been divine shepherds of humanity. They have established a bond of love and unity among mankind, made scattered peoples one nation and wandering tribes a mighty kingdom. They have laid the foundation of the oneness of God and summoned all to universal peace."
