The Church in its Unity Speaks the Language of Every Nation
The disciples spoke in the language of every nation. At Pentecost God chose this means to indicate the presence of the Holy Spirit: whoever had received the Spirit spoke in every kind of tongue. We must realise, dear brothers, that this is the same Holy Spirit by whom love is poured out in our hearts. It was love that was to bring the Church of God together all over the world, and, as individual men who received the Holy Spirit, speaks in the language of every people.
Therefore if somebody should say to one of us, “You have received the Holy Spirit, why do you not speak in tongues?” his reply should be, “I do indeed speak in the tongues of all men, because I belong to the body of Christ, that is, the Church, and she speaks all languages. What else did the presence of the Holy Spirit indicate at Pentecost, except that God’s Church was to speak in the language of every people?”
This way is the way in which the Lord’s promise was fulfilled: No one puts new wine into old wineskins. New wine is put into fresh skins, and so both are preserved. So when the disciples were heard speaking in all kinds of languages, some people were not far wrong in saying: They have been drinking too much new wine. The truth is that the disciples had now become fresh wineskins, renewed and made holy by grace. The new wine of the Holy Spirit filled them, so that their fervour brimmed over and they spoke in manifold tongues. By this spectacular miracle they became a sign of the Catholic Church, which embraces the language of every nation.
Keep this feast, then, as members of the one body of Christ. It will be no empty festival for you if you really become what you are celebrating. For you are the members of that Church which the Lord acknowledges as his own, being himself acknowledged by her, that same Church which he fills with the Holy Spirit as she spreads throughout the world. He is like a bridegroom who never loses sight of his own bride; no one could ever deceive him by substituting some other woman.
To you men of all nations, then who make up the Church of Christ, you the members of Christ, you, the body of Christ, you, the bride of Christ – to all of you the Apostle addresses these words: Bear with one another in love; do all you can to preserve the unity of the Spirit in the bond of peace. Notice that when Paul urges us to bear with one another, he bases his argument on love, and when he speaks of our hope of unity, he emphasises the bond of peace. This Church is the house of God. It is his delight to dwell here. Take care, then, that he never has the sorrow of seeing it undermined by schism and collapsing in ruins.
From a sermon by a sixth century African author
Father of light,
from whom every good gift comes,
send your Spirit into our lives
with the power of a mighty wind,
and by the flame of your wisdom open our minds.
Loosen our tongues to sing your praise
in words beyond the power of speech,
for without your Holy Spirit
we could never speak words of peace
or announce the truth that Jesus is Lord;
who lives and reigns with you and the Holy Spirit,
one God, for ever and ever.
