[W]hen I speak, think and act like a Christian, I do not stay closed off within myself – but I do so in everything and starting from everything: thus the Holy Spirit, the Spirit of unity and truth, can continue to resonate in people's hearts and minds, encouraging them to meet and welcome one another. Precisely because it acts in this way, the Spirit introduces us to the whole truth, who is Jesus, and guides us to examine and understand it. We do not grow in understanding by closing ourselves off inside ourselves, but only by becoming capable of listening and sharing, in the “ourselves” of the Church, with an attitude of deep personal humility. Now it is clearer why Babel is Babel and Pentecost is Pentecost. Where people want to become God, they succeed only in pitting themselves against each other. Where they place themselves within the Lord's truth, on the other hand, they open themselves to the action of his Spirit which supports and unites them. ...
Saint Paul lists the works of the flesh: they are the sins of selfishness and violence, like hostility, discord, jealousy, dissent. These are thoughts and actions that do not allow us to live in a truly human and Christian way, in love. This direction leads to us losing our life. The Holy Spirit, though, guides us towards the heights of God, so that, on this earth, we can already experience the seed of divine life that is within us. Saint Paul confirms it: “The fruit of the Spirit is love, joy, peace”. We note how the Apostle uses the plural to describe the works of the flesh that provoke the loss of our humanity – while he uses the singular to define the action of the Spirit, speaking of “the fruit”, in the same way as the dispersion of Babel contrasts with the unity of Pentecost.
Dear friends, we must live according to the Spirit of unity and truth, and this is why we must pray for the Spirit to enlighten and guide us to overcome the temptation to follow our own truths, and to welcome the truth of Christ transmitted in the Church.
