High Christology is the study of Jesus Christ, by looking at him as first, the divine son of God, and then moving downward to the view of him as a human. It is also known as descending Christology.
Christology studies the person of Jesus, both his divine nature and his humanity. The contrasting study of low Christology is the study of Jesus beginning with his human life and moving upward into his relationship with God. This is also known as ascending Christology. Together, these two fields contribute to a very thorough view of Jesus from a religious standpoint. It can become a very detailed and complex topic.
These two topics can be found in the biblical books of John and Mark. John represents high Christology, and Mark represents the low version. This can be easily identified in the texts from the words used to describe Jesus. An example of this is in John 1:14, where the author states, "the Word became flesh and made his dwelling among us."
