On Wednesday, Father Seraphim mentioned how a Christian cannot think of the expulsion from paradise without thinking of the remedy - the holy Cross. Likewise, we should not think of the confusion of tongues without thinking of the remedy - the coming of the Holy Spirit on the day of Pentecost. While the division caused by the confusion of tongues was for our benefit, it was not in line with God's plan for us. Made in His image, we are made to be united to Him and to one another, as the Father, Son and Holy Spirit are one within the Godhead.
And thus, the Holy Spirit comes down on the day of Pentecost to unite us to Christ and to one another in the Church. Moreover, we each received this very same gift on the day of our baptism, being united to Christ's Body in the Church, and we renew this union each time we partake of the Holy Mysteries.
Father Tom Soroka, speaking of this in his daily scriptural commentary (http://ancientfaith.com/podcasts/thepath), quotes in particular the following hymn from the Pentecost service: "Of old the tongues were confounded / because of the audacity in the building of the tower, / but now the tongues are made wise / because of the glory of Divine knowledge. / There God condemned the impious because of their offense, / and here Christ hath enlightened the fishermen by the Spirit. / At that time the confusion of tongues was wrought for punishment, / but now the concord of tongues hath been inaugurated // for the salvation of our souls" (Aposticha for Pentecost).
Let us give thanks to God for His great mercies! And let us strive to come together, through prayer and repentance uniting ourselves to the Holy Church, and thereby to each other, that we may see fulfilled Christ's last with for us: "that they may be one, as we [the Holy Trinity] are" (John 17).
