“Babylonian confusion” —  this is how we call a situation of disorder, noise and mess in a crowd of unacquainted people. But why “Babylonian confusion”?
The Lord said, "If they have begun to do this as one people speaking the same language, then nothing they plan to do will be impossible for them. Come, let us go down and confuse their languages so they may not understand each other."
Unity of people and nations in one common true belief is the Lord’s almighty power and love. If pride and hatred separate people, God’s power leads them to unity, and this is why the Church founded by Jesus Christ stands firm.
