Today we celebrate Trinity Sunday, which is officially called “The Solemnity of the Most Holy Trinity”.
The Solemnity is one of the few celebrations of the Church’s Year that commemorates a reality and doctrine rather than a person or event. On Trinity Sunday, we remember and honour the eternal God: the Father, the Son, and the Holy Spirit.
The Trinity is described as a “mystery.” By mystery the Church does not mean a riddle, but rather that the Trinity is a reality above our human comprehension that we may begin to grasp, but ultimately must know through worship, symbol, and faith. It has been said that mystery is not a wall to run up against, but an ocean in which to swim.
The Trinity is best described in the Niceno-Constantinopolitan Creed, commonly called the Nicene Creed which we recite each Sunday at Mass. On this Sunday, we are invited to reflect more deeply on this mystery at the heart of our faith.
