"I want to know Christ, yes, to know the power of his resurrection and participation in his sufferings, becoming like him in his death, and so, somehow, attaining to the resurrection from the dead." (Philippians 3:10-11)
Paul warns against those who mutilate the flesh, the circumcision party. He could place confidence in the flesh if anyone could: circumcised on the eighth day, from the tribe of Benjamin, a Hebrew of Hebrews, a Pharisee, faultless in keeping the Law. But whatever was profit to him he now considers loss for the sake of Christ. More than that, he considers everything a loss because of the surpassing worth of knowing Christ Jesus his Lord, for whose sake he has lost all things and considers them garbage, that he may gain Christ and be found in him, not having a righteousness of his own from the Law but that which is through faith in Christ. I want to know Christ, yes, to know the power of his resurrection and participation in his sufferings, becoming like him in his death, and so, somehow, attaining to the resurrection from the dead. The Catechism identifies participation in Christ's sufferings as the most intimate form of union with him available in this life: sharing in his Passion is sharing in his life (CCC 1505).
Not that Paul has already obtained all this or been made perfect, but he presses on to take hold of that for which Christ Jesus took hold of him. Forgetting what is behind and straining toward what is ahead, he presses on toward the goal to win the prize for which God has called him heavenward in Christ Jesus. His citizenship is in heaven. He eagerly awaits a Saviour from there, the Lord Jesus Christ, who will transform his lowly body to be like his glorious body by the power that enables him to bring everything under his control.
Brothers and sisters, what is on your balance sheet of achievements? Paul had an impressive one: tribal purity, legal faultlessness, religious zeal. He called it all garbage. Not because those things were bad but because they were competing with Christ for the place that only Christ can occupy. What is on your balance sheet that is functioning as a rival to the surpassing worth of knowing him?
Lord Jesus, let everything else be loss compared to the surpassing worth of knowing you. Give us Paul's desire: to know you, to know the power of your resurrection and the fellowship of your sufferings, to be conformed to your death, and so to attain the resurrection. Through Christ our Lord. Amen.
