Metaphysical meaning of Son of God (mbd)
Son of God--Son of man--Christ.
Meta. Jesus represents God's idea of man in expression (Son of man); Christ is that idea in the absolute (Son of God). The Christ is the man that God created in His image and likeness, the perfect-idea man, and is the real self of all men.
Christ is the one and only complete, ideal man in the mind of the everywhere present God; the "only begotten Son of God" and "hid with Christ in God." The "Son of man" is the thought of this spiritual man, or idea of God, and like all thoughts is subject to the limitations of its own identity. By voluntarily casting off these limitations the man identity may come into realization of its own universality as the only begotten of God. So we find Jesus referring to Himself as both the "Son of God" and the "Son of man," because He had reached a place in understanding where He realized His relation to Being. In John 7:29 Jesus explains this realization when He says, "I know him; because I am from him, and he sent me."
