WCF 8.7.
Christ, in the work of mediation, acts according to both natures, by each nature doing that which is proper to itself; (Heb. 9:14, 1 Pet. 3:18) yet, by reason of the unity of the person, that which is proper to one nature is sometimes in scripture attributed to the person denominated by the other nature. (Acts 20:28, John 3:13, 1 John 3:16)
