Ver. 3. — Know ye not, that so many of was were baptized into Jesus Christ, were baptized into His death?
In the verse before us, the Apostle proves that Christians are dead to sin, because they died with Christ. The rite of baptism exhibits Christians as dying, as buried, and as risen with Christ. Know ye not. — He refers to what he is now declaring as a thing well known to those whom he addresses. Baptized into Jesus Christ. — By faith believers are made one with Christ: they become members of His body. This oneness is represented emblematically by baptism. Baptized into His death. — In baptism, they are also represented as dying with Christ. This rite, then, proceeds on the fact that they have died with Him who bore their sins. Thus the satisfaction rendered to the justice of God by Him, is a satisfaction from them, as they are constituent parts of His body. The believer is one with Christ as truly as he was one with Adam — he dies with Christ as truly as he died with Adam. Christ’s righteousness is his as truly as Adam’s sin was his. By a Divine constitution, all Adam’s posterity are one with him, and so his first sin is really and truly theirs. By a similar Divine constitution, all Christ’s people are one with Him, and His obedience is as truly theirs as if they had yielded it, and His death as if they had suffered it. When it is said that Christians have died with Christ, there is no more figure than when it is said that they have died in Adam...Ver. 4. — Therefore we are buried with him baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
The death of Christ was the means by which sin was destroyed, and His burial the proof of the reality of His death. Christians are therefore represented as buried with Him by baptism into His death, in token that they really died with Him; and if buried with Him, it is not that they shall remain in the grave, but that, as Christ arose from the dead, they should also rise. Their baptism, then, is the figure of their complete deliverance from the guilt of sin, signifying that God places to their account the death of Christ as their own death: it is also a figure of their purification and resurrection for the service of God.
