“We believe that our most gracious God, in His admirable wisdom and goodness, seeing that man had thus thrown himself into physical and eternal death and made himself wholly miserable, was pleased to seek and comfort him, when he trembling fled from His presence, promising him He would give His Son (who would be born of a woman [Gal. 4:4]), to bruise the head of the serpent (Genesis 3:15) and to make him blessed” (BC, article 17). By this covenant of grace, God offers sinners salvation by Jesus Christ; requiring of them faith in Him that they may be saved. Faith in Christ has always been the only way of salvation, in both Old Testament and New Testament (Romans 4:19-24).
“We confess, therefore, that God has fulfilled the promise which He made to the fathers by the mouth of His holy prophets, when He sent into the world, at the time appointed by him, His own only-begotten and eternal Son,” who took upon Himself the very nature of man, soul and body, with all its weaknesses, except for sin, “being conceived in the womb of the blessed virgin Mary by the power of the Holy Spirit without the means of man” (BC, article 18).
“We believe that by this conception the Person of the Son of God is inseparably united and connected with the human nature; so that there are not two Sons of God, nor two Persons, but two natures united in one single Person.” The divine nature “remained un-created, without beginning of days or end of life, filling heaven and earth,” and the human nature “remained a creature, having beginning of days, being a finite nature, and retaining all the properties of a real body….Wherefore we confess that He is very God and very man: very God by His power to conquer death; and very man that He might die for us according to the weakness of His flesh” (BC, article 19). Jesus Christ is the eternal Son of God in human flesh, the only Mediator between God and Man (1 Timothy 2:5).
“God, who is perfectly merciful and just, sent His Son to assume the nature in which the disobedience was committed, …to bear the punishment of sin by His most bitter passion and death. God therefore manifested His justice against His Son when He laid our iniquities upon Him, and poured forth His mercy and goodness on us, who were guilty and worthy of damnation, out of mere and perfect love, giving His Son unto death for us, and raising Him for our justification, that through Him we might obtain immortality and life eternal [Romans 4:24-25]” (BC, article 20).
The Lord Jesus rose from the dead and ascended into heaven, to receive a universal kingdom over all things (Daniel 7:13-14; Ephesians 1:20-23), in order to save all who believe in Him from every tongue, tribe, and nation, and to destroy all who oppose His kingdom of redemption.
We proclaim to the world that we have no access to God except through the only Mediator, Jesus Christ. For “Christ Himself says: I am the way, the truth, and the life. No one comes to the Father except through Me (John 14:6).” Therefore, let us not seek for another Mediator. “For there is no creature, either in heaven or on earth, who loves us more than Jesus Christ;” indeed, “whom could we find who loved us more than He who laid down His life for us, even while we were His enemies (Rom. 5:8,10)?” (BC, article 26).
