Today we celebrate the solemnity of the Most Holy Trinity. The Church sets aside this Sunday to focus our attention on the mystery of the Blessed Trinity, God who is one, but three persons—Father, Son, and Holy Spirit.

In today’s responsorial psalm the Church sings out: “Lord, send out your Spirit, and renew the face of the earth.” All three readings describe how God has answered that prayer already.

poral experience of the early community, made it seem that Jesus’ resurrection and his ascension were inseparable aspects of a single mystery. Only in the later writings of Luke and John has further theological reflection helped the Christian community to distinguish different dimensions of the mystery. Liturgical tradition has followed the forty-day chronology formulated by Luke. We would miss the point, however, if we were to demand a precise historical chronology of events such as the Resurrection-Ascension that are primarily spiritual in nature and that clearly surpass the bounds of time and space as we know them.

We have a unique episode in the Acts of the Apostles today. A whole roomful of people are baptized with the Holy Spirit before they are baptized with water! The verb used—“the Holy Spirit ‘fell’ on them” (Acts 10:44)—is characteristic of the way the Spirit works throughout the book of Acts: powerful and surprising. Though this “baptism” is not the normative way the New Testament describes baptism, it is still a good reminder today that the Holy Spirit is not controlled by whether or not we pour water, but rather that our sacramental signs reveal the presence of the Spirit at work among us.

Few of us, even when we meditate on the image of the vine and branches, stop to really think about how God “prunes” us. For some there is the danger of thinking that we are already producing fruit for the kingdom, in deed and truth as John says, perhaps raising a family, being active in our parish, and so on. But even those branches which are bearing fruit, the Gospel tells us, can be pruned to produce still more.
