24 Now I rejoice in my sufferings for your sake, and in my flesh I complete what is lacking in Christ’s afflictions for the sake of his body, that is, the church"Col 1:24
Is Paul saying the sacrifice of Jesus was not sufficient?
What is Paul saying I have never been able to understand this passage and I have never heard the catholic understanding of it.
Jesus has made us heirs, and he has promised that we will share in His divine mission to reconcile the world to Himself. This involves participation in his sufferings as well. It does not mean that His sacrifice on the cross was in any way insufficient. It means that when we add our sufferings to His, we become partakers of his grace. This is the whole foundation for the Catholic saying “offer it up”.
2 Cor 11:22-31
23 Are they servants of Christ? I am a better one - I am talking like a madman - with far greater labors, far more imprisonments, with countless beatings, and often near death. 24 Five times I have received at the hands of the Jews the forty lashes less one. 25 Three times I have been beaten with rods; once I was stoned. Three times I have been shipwrecked; a night and a day I have been adrift at sea; 26 on frequent journeys, in danger from rivers, danger from robbers, danger from my own people, danger from Gentiles, danger in the city, danger in the wilderness, danger at sea, danger from false brethren; 27 in toil and hardship, through many a sleepless night, in hunger and thirst, often without food, in cold and exposure. 28 And, apart from other things, there is the daily pressure upon me of my anxiety for all the churches. 29 Who is weak, and I am not weak? Who is made to fall, and I am not indignant? 30 If I must boast, I will boast of the things that show my weakness. "
Paul had some things happen to him that Jesus never did. Does that make Jesus suffering insufficient? By no means. But Jesus has allowed Paul, as He has allowed all of us, to partake of His suffering on behalf of the church, and on behalf of the world.
Phil 3:10-11
10 that I may know him and the power of his resurrection, and may share his sufferings, becoming like him in his death, 11 that if possible I may attain the resurrection from the dead."
When we pray that we may know him, we become united with him in the power of HIs resurrection, and the fellowship of his sufferings.
I recommend the thread on “WORKS SALVATION” for a good explanation on the finished work of Christ on the cross.
