God our Father, Who by sending into the world the Word of truth and the Spirit of sanctification made known to the human race Your wondrous mystery, grant us, we pray, that in professing the true faith, we may acknowledge the Trinity of eternal glory and adore Your Unity, powerful in majesty. Through our Lord Jesus Christ, Your Son, Who lives and reigns with You in the unity of the Holy Spirit, God, for ever and ever.
God our Father, Who by sending into the world the Word of truth and the Spirit of sanctification – Here we have a majestic portrait of the Blessed Trinity: God our Father, the Word of truth, and the Spirit of sanctification. We should take a few minutes on this Solemnity of the Most Holy Trinity to ponder the mystery of the Trinity, to reach out in gratitude and worship to the Father, Son, and Spirit, three in one. God our Father loves us so much that He gave His only Son, the Word, the way, the truth, and the life, to die on the cross for us. The Father and the Son love us so much that they send their very Love, the Holy Spirit, to guide our journey toward increasing holiness.
Your wondrous mystery – The Trinity is now and will always be a mystery. We will never fully understand how God is three Persons and one God, but we believe and we adore.
we may acknowledge the Trinity of eternal glory – The Catechism beautifully teaches, “The divine persons are really distinct from one another. 'God is one but not solitary.' 'Father', 'Son', 'Holy Spirit' are not simply names designating modalities of the divine being, for they are really distinct from one another: 'He is not the Father Who is the Son, nor is the Son He Who is the Father, nor is the Holy Spirit He Who is the Father or the Son.' They are distinct from one another in Their relations of origin: 'It is the Father Who generates, the Son Who is begotten, and the Holy Spirit Who proceeds.' The divine Unity is Triune” (#254).
and adore Your Unity, powerful in majesty – The Catechism also explains, “The Trinity is One. We do not confess three Gods, but one God in three Persons, the 'consubstantial Trinity.' The divine Persons do not share the one divinity among themselves but each of them is God whole and entire: 'The Father is that which the Son is, the Son that which the Father is, the Father and the Son that which the Holy Spirit is, i.e. by nature one God.' In the words of the Fourth Lateran Council (1215), 'Each of the Persons is that supreme reality, viz., the divine substance, essence or nature'” (#253).
