Trinity Sunday (Year B)
Happily, most well-balanced individuals are attracted to good qualities in other people. Examples of good qualities include holiness, goodness, truth, beauty, honesty and a sense of justice. The ancient Greek philosopher Plato believed that these good qualities exist in perfect Forms, which lie beyond what we can perceive fully; but that we can participate in them – we share in them to a certain degree through our senses and what we can perceive with our minds. So, for example, when we love, our love cannot be absolutely perfect, but it is a genuine sharing in the perfection of love which lies beyond. What we experience of justice, truth, goodness and so on, are not their absolute perfections but a genuine sharing nonetheless.
The idea of participation (from the Greek methexis) became important in the thinking of Christian theologians even before the Middle Ages; and in the thirteenth century, St Thomas Aquinas used the language of participation to indicate the dependent status of human beings in relation to God. We share in His life, and not the other way round. So, the fullness of love, justice, truth, goodness and beauty were understood to be in God; and we share in them through his grace, and to some degree. What we experience of these qualities by sharing are perfections in God. So, this means that, although God is qualitatively different from us, he nevertheless shares his life with us here and now. Through grace, we can grow so as to share these qualities more and more.
Holy Scripture is insistent that God wills to share his life with us, and all three of today’s readings bear this out. Israel is spoken of in the first reading as the Chosen people of God, taken to Himself; St Paul speaks of the baptised as coheirs with Christ and as children of God. In the gospel reading, St Matthew speaks of the commission to share the Good News with ‘all the nations’. God, we can be sure, wants all people to share his life.
Today, we celebrate God as Holy Trinity. Of course, Christians celebrate God as Trinity all the time, as we are reminded right at the start of every Mass; but today’s feast invites us to consider the nature of God as the mystery of three distinct Persons within one godhead. It makes no sense mathematically, of course – three cannot be one in that scheme of things. But the language of love, truth, goodness, beauty and the like gives us a way into the mystery. Some theologians have said that the language of love - as well as that of truth, goodness and so on – provides us with profound insight into the nature of God. The love which binds the Father and the Son and the Holy Spirit is of such sheer perfection that they cannot be other than One. The loving relationships that we know or have known are sharings in, and reflections of, that perfect love which characterises the life within the godhead – and are thus intimately related to it. This enables us to see why the marriage liturgy speaks of two becoming one – in the sacrament of marriage, the spouses remain distinct, but the love between them has an unlimited potential to grow towards the perfect simplicity of oneness.
What all this means is that, even now, we share in the life of God. The sacramental life of the Church is entirely to do with this theme of sharing God’s life. When we come to celebrate the Eucharist, we are not simply gathering for a time of fellowship, as important as that aspect is. More fundamentally, we are gathering to make an offering of ourselves to God and to receive in return what we might describe as an infusion of His risen life in Holy Communion; and this is why it’s so important to prepare carefully.
The sacraments build us up in the life of God. The whole Christian life is a life which is oriented towards the justice, holiness, goodness, truth and beauty of God. Salvation means sharing in God’s own life, being drawn ever more deeply into the relationship between Father, Son and Holy Spirit, and seeing as God sees. Each of us is called by Him to participate in the eternity which is God’s own life. What we do here Sunday by Sunday and day by day is as important as that.
