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 in one Spirit we were all baptized into one body
You are part of a body. Each part of a church is different, every member is unique. If you were just like someone else, one of you would be redundant. It is the Holy Spirit that unites our diverseness. The church isn’t meant to all be the same, we are intended to be different, that’s what makes beautiful harmony, unity from within our diversity. If you are a Christian, you have been baptized into the Church through the Holy Spirit. He is with you, guiding you, and organizing us for his kingdom, for his glory, together.
