Death to sin is the planting in the heart of hatred and aversion toward it. This comes from feeling its bitterness and destructive power, together with feeling the ineffable sweetness of life according to God.
Both of these are born again in the believer before baptism, when he inclines toward faith. Yet they are only dispositions and presentiments. In the mystery of baptism, grace descends upon them and communicates to them divine strength of constancy and power for all time, as long as the will remains on their side.
"In whom also you were raised together through faith in the working of God, who raised Him from the dead." You were raised together in the same place where you were buried together, that is, in holy baptism.
"Baptism is not only a tomb. See what he says: 'In whom also you were raised together'" (Saint Chrysostom). But as the burial together was spiritual, so also the rising together is spiritual.
The former is death to sin. The latter is enlivening for life according to God, so that we might walk in newness of life, as Saint Paul says in the Epistle to the Romans (cf. Rom 6:4).
"In whom," εν ω, may refer both to baptism and to the Lord and Savior. Whichever way it is taken, the thought does not change. Yet the flow of speech requires that it refer to the Lord, because everything is being said about Him.
Blessed Theodoret and Oecumenius refer "you were raised together" to the resurrection from the dead. Blessed Theophylact refers it to both, that is, both to rising in spirit and to the future resurrection.
The first writes: "The Apostle proclaims the resurrection, since we still have mortal nature." Oecumenius says the same: "Having believed that God is able to raise from the dead, you also have risen. For in baptism we have been raised, though only in potentiality, not yet in actuality."
These are the words of blessed Theophylact: "We have risen in the Lord in two ways. We have risen by the hope of the resurrection, so certain that it is as though we had already obtained it, although it is still to come.
"We have also risen spiritually, having cast off the deadness of sin and received enlivening by the spirit."
According to the flow of speech, it is more direct to understand here the spiritual resurrection, or the reception of power to live according to God in renewed life.
For immediately after this (Col 2:13), it is said that God made them, the Colossians, who were dead in sins, alive together with Christ. This is evidently because He made them alive for a life opposed to sin.
"Through faith in the working of God, who raised Him from the dead." If in "you were raised together" one sees the future glorious resurrection received by undoubting hope, then the sense is: by faith in the working of God, that is, in God's omnipotence, that He is able to raise.
He showed this by the example of raising the Lord and Savior. Thus blessed Theodoret says: "Believing in the power of God, we await the resurrection, having as our pledge the resurrection of the Master Christ." Blessed Theophylact repeats the same.
But if in "you were raised together" one sees resurrection in spirit, or enlivening for life according to God, then the sense is this. You rose together because of your faith, by the action of God, who raised Christ the Savior from the dead.
You rose spiritually by divine action received through faith. This action is the same in kind as that by which Christ the Lord rose from the dead.
Saint Paul also sets them side by side in the Epistle to the Romans: "We were buried with Him through baptism into death, that as Christ was raised from the dead by the glory of the Father, so we also should begin to walk in newness of life" (cf. Rom 6:4).
Ambrosiaster partly understands this in this way. Blessed Theophylact remarks that, although Christ's resurrection is here attributed to God the Father, nevertheless it is also the action of the Lord Jesus Himself.
"Christ," says the Apostle, "having accepted bodily death, was made alive by the Father." He speaks this way not because Christ the Lord was Himself too weak to make Himself alive, but in order to refer all things to one source.
That the Lord's resurrection is also His own action, He Himself says: "In three days I will raise it up," speaking of the temple of His body (cf. Jn 2:19). In Acts it is also said that after His Passion He presented Himself alive (cf. Acts 1:3).
Our spiritual resurrection is not accomplished by the action of God the Father alone. It is accomplished according to the good pleasure of God the Father, in the sanctification of the Spirit, for obedience and sprinkling with the Blood of Jesus Christ (cf. 1 Pet 1:2).
Oecumenius, while explaining spiritual circumcision, draws an inference concerning the action of the Most Holy Trinity in it.
