Humanity is at its best in today’s first reading. Pentecost brought about a wonderful bonding of people from all over the Roman Empire. They were united in admiring and praising the marvels of God. In spite of differences of language and culture there was a real communion among them. Wherever communion of heart and mind exist among people of different backgrounds, the Holy Spirit is at work. Unity in diversity is the mark of the Spirit. Jesus points out another manifestation of the Spirit: the pursuit of truth. Only the Spirit can lead us to the complete truth. If someone is genuinely seeking for truth, and willing to engage in good works with others, there the Spirit is at work. Fullness of truth and love is always beyond us; but the Spirit is given to lead us towards the complete truth and love, in all its height and depth.
