The Mystical Body of Christ

I do not have any statistics, but I believe that chapters 12, 13 of the first epistle to the Corinthians are the most quoted chapters of St. Paul's epistles. Chapter 12 expounds an organic view of the church and chapter 13 is an ode to charity.
First of all, St. Paul discusses the different gifts each member received from the Holy Spirit. In order to help believers stick together in one church, the Holy Spirit empowers the church members in different ways in order to help build them up into one church. The gifts of the Holy Spirit (utterance of wisdom, utterance of knowledge, faith, healing, miracles, prophecies, the discernment of spirits and speaking in tongues) are for the common good, for the building up of the church. Therefore, possession of these special talents is nothing to boast about. They come from the same Holy Spirit for the building of the church. Yet, boasting is a reality in life and boasting is the source of factionalism which Paul tried to eradicate.
To each is given the manifestation of the Spirit for the common good (1 Corinthians 12:7).
St. Paul continues to expound his theology of the church being the Mystical Body of Christ. We are all members of this Body. Together, members form an organic whole. They are interdependent. Therefore, there should NOT be any discrimination against any members.
For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ.
For by one Spirit we were all baptized into one body -- Jews or Greeks, slaves or free -- and all were made to drink of one Spirit (1 Corinthians 12:12-13).
However, there are a few verses which are quoted less frequently.
On the contrary, the parts of the body which seem to be weaker are indispensable,
and those parts of the body which we think less honorable we invest with the greater honor, and our unpresentable parts are treated with greater modesty,
which our more presentable parts do not require (1 Corinthians 12:22-24a).
Here, St. Paul was not very explicit. There is no way to determine what those "weaker", "less honourable" members Paul referred to. Back to our physical body, which parts of the physical body are weaker and yet indispensable? Quickly, one would answer: the tongue. It is not as hard as bones or teeth. Without it, we cannot articulate our thoughts and feelings. It is truly indispensable for normal life.
To wrap up chapter 12, Paul ranked the different offices in the Church!
And God has appointed in the church first apostles, second prophets, third teachers, then workers of miracles, then healers, helpers, administrators, speakers in various kinds of tongues (1 Corinthians 12:28).
The gifts and duties are different and serve different purposes. Since they all serve one purpose, they should be treated equally with respect. A big organization demands a division of labour. Then, a hierarchy began to emerge, with the apostles at the zenith.

My dear Advocate, I thank my sweet Jesus for his tolerance and patience in accepting us to make up his Mystical Body. We are unworthy to be absorbed into You. Pray that our words and actions will not tarnish Your glory. Amen.
