What doctrine describes Jesus as fully God and fully man in one Person?

• A. Nature
• B. Hypostatic Union
• C. Incarnation
• D. Redemption

Answer: (B)

The main idea here is how Jesus can be both truly God and truly human in one person. The term that describes this precise unity is the hypostatic union. In this view, Jesus has two complete natures—divine and human—united in a single person. They are not blended into a new third nature, nor separated into two distinct persons. This allows Jesus to be fully God—eternal, all-powerful—while also fully human—born, grew up, experienced temptation, suffered, and died. The two natures remain distinct but operate together in harmony within one Person.

The word incarnation focuses on God becoming flesh, but the description about one Person with two complete natures is specific to the hypostatic union. A general term like nature is too broad, and redemption describes what Jesus accomplishes for salvation rather than how his person and natures relate.
