^"But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you." (John, 14, 26) "They saw what seemed to be tongues of fire that separated and came to rest on each of them. All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them." (Acts 2, 3-4) The window depicts Tower of Babel (at the bottom part) "Now the whole world had one language and a common speech. /.../ Then they said, ?Come, let us build ourselves a city, with a tower that reaches to the heavens /.../ The Lord said /.../ Come, let us go down and confuse their language so they will not understand each other.? So the Lord scattered them from there over all the earth" (Genesis, 11, 1-8) A juxtaposition of these two scenes shows the uncertainty of building without God's presence and the power of building with Him. It also highlights the unifying power of the gifts of the Holy Spirit. The tongues of fire set upon each of the apostle and the gift of tongues they received symbolizes the true unity with God. By then the apostles can use the languages to bear the witness to the people around the world and together build the true Church of God. The Church that contrary to Tower of Babel reunites the people in God's love and freedom.
