We are taught that Jesus was the only begotten son of God (John 1:14, 18; 3:16, 18; 1 John 4:9). While this is true, probably our understanding of ‘only begotten’ isn’t correct. The Old Testament tells us about the Sons (plural) of God. We are also taught that God is our Father in the New Testament. (Jesus refers to him as my God, and your God; my Father, and your Father.) Job talks about the sons of God shouting for joy at the creation of the earth.
Monogenes is the Greek word translated by this phrase. The term means “one of a kind” or “unique”. It does not mean that Jesus was God’s only son. It means he was unique among God’s sons.
To demonstrate this… let’s look at Abraham and Isaac. In Hebrews 11:17, Isaac is called Abraham’s monogenes. Clearly, Isaac was not Abraham’s only son. Before Isaac, Abraham had Ishmael. But Isaac was Abraham’s unique son. He was the son of the covenant, or promise. He was the line in which Jesus would come.
We are God’s spirit-children, the elohim. We have descended to earth to be embodied, just like Jesus was embodied. But he had a unique mission, a mission to save us all from death. He is the gateway back to our Father in heaven.
