The Holy Trinity is not an easy subject to blog on. First, where do you start? Perhaps something of a rhetorical trick question, as reflecting on any person of the Trinity inevitably leads us to the others. For example, we know God the Father though the teaching and works of God the Son, which we understand through the inspiration of God the Holy Spirit. Similarly, we pray to the Father, through the Son, in the unity of the Holy Spirit.
Another aspect of the Trinity is that it is possibly the greatest example of a mystery, in the spiritual sense, and as such, is in direct contrast to the position of the atheists and materialists who maintain that human reason alone will ultimately lead us to an understanding of everything. A mystery is defined as 'A truth which is above reason, but which has been revealed by God'. In other words, we can't work everything out for ourselves, or put another way, we can believe more than we can understand.
This is summed up in the legend in which St. Augustine, having been working on a book about the Trinity, is walking by the seashore and sees a small boy trying to empty the sea of water, using a spoon. When the Saint remarks on the futility of the task, he receives a reply to the effect that, 'I shall do this in less time than you will come to a full understanding of the Trinity'
So let's not get too worried when, at times, we find issues of our Faith hard to get to grips with. We need to trust in, and love, Our Lord, and accept that some things just are. They are because God wants it so, and sometimes it is beyond us to understand the 'how' and the 'why'.
Gloria Patri, et Filio, et Spiritui Sancto:
Sicut erat in principio, et nunc, et semper,
et in saecula saeculorum.
