The Hypostatic Union is the term used to designate the two natures of Jesus; it’s the union of his two natures. One nature is fully diving and the other one is fully human. This doctrine teaches that these two natures both are united in one person in the God-man. However, although Jesus has two natures he is still one person; we shouldn’t confuse that.
The New Testament teaches that Jesus is equal with God (John 8:58, 10:30) but that he also became a person (John 1:14). We see Jesus’ equality with God through his receiving of worship (Matt. 2:2, 11, 14:33), that he was prayed to (Acts 7:59), his sinlessness (1 Pet. 2:22, Hebrews 4:15), omniscience (John 21:17), and deity (Col. 2:9). We are also informed of Jesus’ limited physical body (John 4:6, 19:28) – we see that Jesus died (Romans 5:8), he grew in wisdom (Luke 2:52), he was tempted (Matt. 4:1), and that he prayed to God the Father (John 17). Accepting the message of the New Testament clearly suggests that Jesus is both divine and human.
However, this is, on its face, a really simple concept, but we also shouldn’t expect to understand it fully (by that I don’t mean that we shouldn’t probe it, investigate it and provide answers to challenges, but that we will never fully understand it in all its depth). For example, how is it possible that an infinite God can become a finite man in Jesus Christ? How did Jesus exist eternally prior to his virginal conception? These are questions that have been tackled by some of the leading Christian thinkers throughout history as well as today. It is also true that Christians need to have answers for the doctrines proposed by Christian Scientists and Jehovah’s Witnesses that warp the biblical message. That and more will be our focus over the next few weeks and months.
