God the Son, the second Person of the Blessed Trinity, has eternally co-existed with God the Father and God the Holy Spirit. The God-man, Jesus Christ, has existed from the time of his Incarnation within the Blessed Virgin Mary. In other words, because he is God, God the Son has always existed; but at his Incarnation, God the Son assumed a human nature and became the man who would be known as Jesus of Nazareth, while still retaining his divine nature and remaining the eternal God the Son.
