"Now you are the body of Christ, and each one of you is a part of it." (1 Corinthians 12:27)
Chapter 12 opens the great triptych on spiritual gifts, love, and worship that occupies chapters 12-14. There are different kinds of gifts but the same Spirit; different kinds of service but the same Lord; different kinds of working but the same God who works all of them in everyone. The Spirit distributes gifts to each one: wisdom, knowledge, faith, healing, miraculous powers, prophecy, distinguishing between spirits, speaking in tongues, interpretation. All are the work of one and the same Spirit who gives them to each person as he determines. The Catechism identifies the charisms as graces of the Holy Spirit given for the benefit of the whole Church, not primarily for the personal sanctification of the recipient (CCC 2003).
Paul develops one of his most enduring images: the Church as the body of Christ. Just as the body has many parts but is one body, so it is with Christ. For we were all baptised by one Spirit into one body, whether Jews or Gentiles, slave or free, and we were all given the one Spirit to drink. The eye cannot say to the hand: I don't need you. The head cannot say to the feet: I don't need you. On the contrary, those parts of the body that seem weaker are indispensable, and those parts we think are less honourable we treat with special honour. God has arranged the body so that there should be no division, but that its parts should have equal concern for each other. If one part suffers, every part suffers; if one part is honoured, every part rejoices. Now you are the body of Christ, and each one of you is a part of it.
The Catechism calls the Church the body of Christ in its fullest theological sense: not merely a metaphor but a sacramental reality. The Church participates in the life of Christ through the Holy Spirit, and every member of the Church is genuinely a member of Christ's body with a real function in the whole (CCC 790).
Brothers and sisters, the parts of the body that seem weaker are indispensable. The member of your parish who appears least gifted, least prominent, least visible, is indispensable to the body. The eye cannot say to the hand I have no need of you. Your next act of ministry might be to find the part of the body that feels unnecessary and tell them what the whole body loses without them.
Lord God, you arranged the body so that there should be no division but equal concern for each part. Heal every division in your Church. Make us feel what each other feels: if one suffers, all suffer; if one rejoices, all rejoice. Let us be truly the body of Christ. Through Christ our Lord. Amen.
