Final answer:
The discipline of Christology regards the Incarnation as Jesus Christ's embracing of humanity while maintaining full divinity, which is pivotal for Christian salvation.
Step-by-step explanation:
The discipline of Christology deals with the study and understanding of the nature and work of Jesus Christ. In this context, the term Incarnation refers to the Christian belief that Jesus Christ, the Word of God, became flesh and lived among us. The correct answer to the question about the Incarnation pointing to the Word is not about a) Losing divinity or d) Rejecting humanity, but rather b) Absorbing humanity or, more accurately, c) Embracing humanity. The Incarnation means that while Jesus remained fully divine, he also became fully human to achieve the salvation of humankind. This theological concept is central to Christianity as it signifies that through Jesus's life, death, and resurrection, the possibility of eternal life in heaven is offered to humanity.
