Not long after this, however, while "still breathing murderous threats against the disciples of the Lord," he encounters the glorious risen Lord Jesus Christ who says to him, "Saul, Saul, why are you persecuting me?" (Acts 9:1, 4). These mysterious words of the risen Lord contain an understanding of the church that Saul, now Paul, would try to teach the rest of his life. Jesus did not ask him, "Why are you persecuting my church?" Jesus asked him "Why do you persecute me?" Somehow, some way, Christ and the church are so intimately one, so united, that his persecution of the church was a persecution of Christ.
St. Paul teaches first that Christ "is the head of the body, the Church" (Colossians 1:18). Christ is preeminent in everything.
We learned from a previous column (August 2008) what St. Paul teaches of Jesus. Jesus, who is fully God and fully man, is the head of the body of the church. In Ephesians, Paul tells us that it is the Father who "put all things beneath his feet and gave him as head over all things to the church, which is his body…" (1:22-23).
We might ask at this point how, in fact, we become part of the Body of Christ the head. St. Paul in no way leaves us grasping for answers.
He says clearly, "For in one Spirit we were all baptized into one body…" (1 Corinthians 12:13). Through baptism we are so united with Christ so as to become his very body. The Father and the Son send the Spirit in baptism to make us one in Christ. St. Augustine would one day say, "What the soul is to the human body, the Holy Spirit is to the Body of Christ, which is the Church" (Catechism of the Catholic Church 797).
However, beyond baptism, the church becomes more and more united to Christ through Christ’s self-sacrifice made present for us in the Eucharist. "The cup of blessing which we bless, is it not a participation [communion] in the blood of Christ? The bread that we break, is it not a participation in the body of Christ? Because the loaf of bread is one, we, though many, are one body, for we all partake of the one loaf" (1 Corinthians 10:16-17). We become one body with Christ through the power of the Holy Spirit in baptism, but we continue to come into a more intimate communion with Christ the head through receiving his body, blood, soul, and divinity.
