Commentary:
- Jesus Christ our Lord perfectly accomplished the work the Father
gave Him to do (cf. John 17:4); as He said Himself when He was about to
die, “It is finished”, it is accomplished (John 19:30).
From the point onwards objective redemption is an accomplished fact.
All men have been saved by the redemptive death of Christ. However,
St. Paul says that he completes in his flesh “what is lacking in
Christ’s afflictions”; what does he mean by this? The most common
explanation of this statement is summarized by St. Alphonsus as
follows: “Can it be that Christ’s passion alone was insufficient to
save us? It left nothing more to be done, it was entirely sufficient
to save all men. **However, for the merits of the Passion to be applied
to us, according to St. Thomas (“Summa Theologiae”, III, q. 49, a. 3),
we need to cooperate (subjective redemption) by patiently bearing the
trials God sends us, so as to become like our Head, Christ” ** (St.
Alphonsus, “Thoughts on the Passion”, 10).
St. Paul is applying this truth to himself. Jesus Christ worked and
strove in all kinds of ways to communicate His message of salvation,
and then He accomplished the redemption by dying on the Cross. The
Apostle is mindful of the Master’s teaching and so he follows in His
footsteps (cf. 1 Peter 2:21), takes up his cross (cf. Matthew 10:38)
and continues the task of bringing Christ’s teaching to all men.
Faith in the fact that we are sharing in the sufferings of Christ,
[Pope] John Paul II says, gives a person “the certainty that in the
spiritual dimension of the work of Redemption he is serving, like
Christ, the salvation of his brothers and sisters. Therefore he is
carrying out an irreplaceable service. In the Body of Christ, which is
ceaselessly born of the Cross of the Redeemer, it is precisely
suffering permeated by the spirit of Christ’s sacrifice that is the irreplaceable mediator and author of the good things which are
indispensable for the world’s salvation. **It is suffering, more than
anything else, which clears the way for the grace which transforms
human souls. Suffering, more than anything else, makes present in the
history of humanity the force of the Redemption” ** (“Salvifici Doloris”,
27).
