This weekend we celebrate Trinity Sunday which is all about the triune god Father, son and Holy Spirit. When my Father was alive he often had a small tin of oil in the tool box he used which was called three in one oil when I was thinking about a definition of the Holy Trinity it came to mind however the trinity is about three divine persons in one not a tin of oil !!! In the Holy Trinity the Father is equal to the Son and the Son is equal to the Spirit three in one and one in three we hear this in the breastplate of St. Patrick. St Patrick, with a brilliance that we Irish are justly celebrate found in the three leaf shamrock rising from the one stem an image of the Trinity which is still used today. The feast of the Trinity goes back to 12th century England and St Thomas a Becket, Archbishop of Canterbury. Historians say the great Thomas celebrated a Liturgy in honor of the Trinity in his cathedral. So was born the observance. In the 14th century, the feast came to be observed by the universal Church.
One week after the end of the Easter season, in which we gave thanks for the saving death and resurrection of Jesus, and the celebration of the gift of the Holy Spirit on Pentecost Sunday, this feast of the Holy Trinity invites us to contemplate the mystery of God to the extent that our minds are able. Paul in the Letter to the Romans reminds us that the Spirit of God makes us God’s children, destined to share in the life of God, as Christ does.
Through the Holy Spirit dwelling in our hearts we become aware of the love and strength of the living God available to us both now and in the life to come. The gospel reading for this Sunday speaks of power: the power of presence and the power of the name. Ancient people placed great weight in presence; the way someone dressed and acted spoke of social power. Ancient people also chose names carefully; they believed a person’s name defined their strength of character. Both outward presence and inward character are part of the disciples’ experience.When the followers saw the resurrected Lord and heard his command to evangelize the entire world, they saw for themselves the Trinity in action. When we live as followers of Christ, we invite others to join us not because they see nice people living good lives. No, they, too, see the Trinity in action as God works through us.
Each Trinity Sunday, we only scratch the surface of this great mystery of our faith. In gratitude and faith, let us begin and end every prayer with greater faith and reverence “In the name of the Father, and of the Son, and of the Holy Spirit. Amen.”
