There is a lesson a lot of multicultural society is to learn, and this is a lesson that we get from what Paul wrote about the Church. However, in a multicultural society there is no head that can direct us with no bias, but the Church has the righteous Judge - Christ Himself as the Head. The lesson is from 1 Corinthians 12.
So the Church is Christ's body. Literally like our physical body, we depend on one another. We have different gifts and none of the gifts are for our own good, but for the common good - the good for the Church as a whole. Here I have to make clear that I am referring to the world wide Church, not the local church. The local church is part of the world wide Church, thus we are to see past the limitations of our own church and see what are we going to do in the body of Christ to support one another, drawing our life source from the Head, listening to His command.
But there are two conditions that hamper the unity of these diverse body parts.
Inferiority
Being inferior, meaning after comparison, you wished you could be someone else. You wished you could have been that awesome speaker, that annointed preacher or the powerful worship leader. But, God has weaved you in your mother's womb. He has made you who you are for a special place in His kingdom. He has given you your family, your place of birth and what you go through as part of His plan to build you up to be a part of His kingdom. You are unique and your gifts are unique too. Identify them, serve with them, and build up the Church.
Superiority
Being superior, it means that you think you are better than others. There is a sense of pride that you are taking to yourself. You think you are the best servant and devoted the most time for God. But, we are all called differently, gifted with different talents. There is no gift that is more important than the others although traditionally the Church has placed teaching and preaching at the highest place - but don't. Instead, see pastors and teachers as your elders - honour them as you would your elder relatives, but don't judge others based on what gifts you think are more important. Then, you can see past the imperfections of every single brother and sister in Christ and start serving with humility.
And, to sum it up, Paul gave the most amazing revelation - love in Chapter 13. For because of God's love we have a life, and because of this love we can love others. What is the Church without love?
