Unity is an essential element of any Christian community. A united community can accomplish a lot specially in the mission that God has given them. Unity is the key of which we can evangelize the world. Also, unity is Jesus’ desire when He prayed to the Father in the Garden of Gethsemane.
A very important ingredient to unity is humility. Without humility of the members of the body, unity is impossible to achieve. Jesus already showed us what true humility is all about.
