"Section II.--The Son of God, the second person in the Trinity, being very and eternal God, of one substance, and equal with the Father, did, when the fulness of time was come, take upon him man's nature, with all the essential properties and common infirmities thereof, yet without sin; being conceived by the power of the Holy Ghost, in the womb of the Virgin Mary, of her substance. So that two whole, perfect, and distinct natures, the Godhead and the Manhood, were inseparably joined together in one person, without conversion, composition, or confusion. Which person is very God and very man, yet one Christ, the only Mediator between God and man. "Section III.--The Lord Jesus, in his human nature thus united to the divine, was sanctified and anointed with the Holy Spirit above measure; having in him all the treasures of wisdom and knowledge; in whom it pleased the Father that all fulness should dwell: to the end that being holy, harmless, undefiled, and full of grace and truth, he might be thoroughly furnished to execute the office of a Mediator and Surety. Which office he took not unto himself, but was thereunto called by his Father; who put all power and judgment into his hands, and gave him commandment to execute the same. "Section IV.--This office the Lord Jesus did most willingly undertake; which that he might discharge, he was made under the law, and did perfectly fulfil it endured most grievous torments immediately in his soul, and most painful sufferings in his body; was crucified, and died; was buried, and remained under the power of death, yet saw no corruption. On the third day he arose from the dead, with the same body in which he suffered; with which he ascended into heaven, and there sitteth at the right hand of his Father, making intercession; and shall return to judge men and angels at the end of the world. "Section VII.--Christ, in the work of mediation, acteth according to both natures; by each nature doing that which is proper to itself; 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. "Section VIII.--To all those for whom Christ hath purchased redemption, he doth certainly and effectually apply and communicate the same: making intercession for them; and revealing unto them, in and by the Word, the mysteries of salvation; effectually persuading them by his Spirit to believe and obey; and governing their hearts by his Word and Spirit; overcoming all their enemies by his almighty power and wisdom, in such manner and ways as are most consonant to his wonderful and unsearchable dispensation" (Westminster Confession of Faith).
