On Pentecost Sunday (June 4th) we celebrated the outpouring of the Holy Spirit, the third 'person' of the Holy Trinity, upon the infant church. On Sunday 11th, we celebrated that most wonderful, but somewhat confusing, feast of the Holy and Undivided Trinity, referring of course to the God who we believe as Christians is both one and also three: Father, Son and Holy Spirit. There are so many analogies that try to explain this intimate relationship, for example water, steam and ice - all one substance, but in three forms; a source, a spring and a stream; brain, thought and word; a clover leaf - three leaves in one. I'm not sure that any of them help us to come near to understanding the extraordinary mystery that is God!
What the idea of God being both one and three, eternally, does tell me though is that God is profoundly relational. He is all about community and relationship - communities and relationships that last. One part of the Trinity doesn't opt out for a while, decide it can't be bothered, or worse, turn to hating the other parts of this community. It is perfect unity. Christians believe that, through the gift of the Holy Spirit, imparted in Baptism, we are caught up into the life of that Holy Trinity, and that perfect community. It is a challenge for us, especially at a time when we see hatred and division in terrorist attacks, and as we face a General Election, and the outworking of the Brexit vote a year ago, to seek not those things that divide us further, but those things that draw us together, and build up community and relationship in a positive and enduring way.
With my best wishes,
