Today we pick up where we left off at Ash Wednesday, we are back in Ordinary Time. Our time for intense celebration and reflection on the works of our Lord gives way to learning how to be His disciples. But first, we attend to two great celebrations next week we celebrate Corpus Christi, and today we celebrate the Holy Trinity.
The Feast of the Holy Trinity is unusual, indeed singular, in the celebrations of the Liturgical Year. Whereas other feasts celebrate actions of Lord such as the Nativity, Good Friday, Easter; or the result of His action such as feast days for saints and our blessed Mother; today we celebrate the very mystery of God. Today, we celebrate who God is, we celebrate the central mystery of the Christian Faith. CCC states:
‘The mystery of the Most Holy Trinity is the central mystery of Christian faith and life. It is the mystery of God in himself. It is therefore the source of all the other mysteries of faith, the light that enlightens them. It is the most fundamental and essential teaching in the “hierarchy of the truths of faith”. The whole history of salvation is identical with the history of the way and the means by which the one true God, Father, Son and Holy Spirit, reveals himself to men “and reconciles and unites with himself those who turn away from sin”’
That is what we are celebrating – the central mystery of our whole faith – it is that important. Out of the infinite aspects we can reflect on – three points come quickly to mind.
First. God has chosen to reveal Himself to us.
He chose to reveal himself to us– this not something we can figure out ourselves. It is God who brought to us who He is. Through history He started to make us aware of who he is. But it is Christ, who makes whole the revelation of who He is.
Second – And reveals to us that He is a Trinity.
‘The Father and the Son and the Holy Spirit. Because that is who He is; One God three persons. There is no other name by which He can go by. Creative as we can be there nothing we can do to repackage this. God is a Holy Trinity, 3 persons in 1 God; He Father, Son and Holy Spirit. Christ said so, the whole bible speaks of this in hidden ways until Jesus proclaims it openly and clearly.
From the meeting of Abraham in Mamre:
‘The Lord appeared to Abraham by the oak of Mamre, as he sat in the entrance of his tent, while the day was growing hot. Looking up, he saw three men standing near him. When he saw them, he ran from the entrance of the tent to greet them; and bowing to the ground, he said: “Sir, if it please you, do not go on past your servant.’
To the words of Christ in John: ‘Whoever has seen me has seen the Father.’ And today’s Gospel and of course Christ’s great commission ‘Go, therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit…’
Three – He is relational.
As creatures we are limited in our ability to explain the unexplainable; but we try. There have been some rather clever attempts throughout history to try and explain what a Holy Trinity is like. We have all heard the comparison credited to St. Patrick of a three leaf clover; or the likening of the Trinity to a piano chord and so on. These comparisons are good as far as they go to describing the unity within the Trinity; but recently, in past 60 years or so, there have other attempts to describe the Trinity; attempts that actually do damage to our understanding.
Creator, Redeemer, Sanctifier or Creator, Liberator, Sustainer have been used. They have not only been used to explain the Trinity but they have, sadly, been used in the Sacrament of Baptism to replace Father, Son and Holy Spirit. These are very disturbing because they reduce the Trinity to actions or jobs, and most importantly, they erase the Trinitarian reality of God. For instance the Father is creator, and so is the Son and the Holy Spirit; The Son is the redeemer and so are the Father and Holy Spirit and the same goes with Sanctifier. Though we attribute some attributes to each of the persons for convenience, as in our opening prayer when we heard ‘the Spirit of sanctification’, in truth all three hold all attributes, as evidenced by the prayer over the offerings we are about to hear: ‘Sanctify by the invocation of your name, we pray, O Lord our God.’ These attempts have caused grave damage to the faithful to the point that Holy Mother Church is requesting those who went through a baptism with these ‘labels’ to be found, for they were not baptized. No, these names are not the same as what God Himself revealed to us – and for that reason alone we should not use them. But, there is a deeper import, revealed to us, for using Father, Son and Holy Spirit.
God is love!!!!!!
Love is relational! God, in His very being is self-giving total love, to be that means to love others just because they are other. The Father loves the Son, He does everything for the Son. The Son likewise, does everything for the Father. And this is so perfect that it is the third person the Holy Spirit. God’s revelation to us as Father, Son and Holy Spirit allows us into the inner part of our creator – not what He does but who He is – Love.
Brothers and sisters, this is why the Catechism says the mystery of the Holy Trinity is central: ‘It is the most fundamental and essential teaching in the “hierarchy of the truths of faith”. God is Love, He offers Himself totally, and all of His revelation and His actions towards us should us bring us to the realization that this is what we should do as well. God has revealed His nature to us to allow us to strive for and participate in it – we are made in His image after all. So, as we start into the great school of discipleship, Ordinary Time, let’s look within and ask ourselves how we are doing in trying to understand the great and central mystery of our faith.
How is our participation in this mystery doing?
How are we in living a life of self-giving love?
Our answers to these questions are the only and true gauge of our understanding this mystery of the Trinity.
