Quote:
“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” (Council of Toledo XI (675)). 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” (Lateran Council IV (1215)). The divine Unity is Triune.~Catechism of the Catholic Church #254
One of the most fiercely debated dogmas of our faith in the early centuries of the Church was on the nature of the Most Holy Trinity. Today’s solemnity did not enter the General Roman Calendar until the fourteenth century, partly because we are called to honor and worship the Most Holy Trinity every day and in every liturgy. But designating one Sunday on which we ponder the inner life of the Most Holy Trinity is an opportunity to renew and deepen our honor and worship.
The Trinity is first and foremost a mystery. As The Divine Mystery above all mysteries, we must begin by humbly acknowledging that we will never, not even in Heaven, have a complete understanding of God’s essence, His inner reality. Only God knows Himself fully. Not even the Blessed Virgin Mary or the highest choirs of angels see Him and know Him as He sees and knows Himself. Nonetheless, every creature, whether angel or human, is called to probe the mysteries of God to the fullest extent possible. In that probing, contemplating, and understanding, we discover the purpose of our lives and experience the fullness of beatitude to which we are called. God and God alone satisfies the hungry, weary, and seeking soul.
This might come as a surprise, but God is perfectly simple. Saint Thomas Aquinas, one of the Church’s greatest teachers, explains that angels, the physical world, and humans are made up of different material and immaterial parts that can change over time, making us a complex reality capable of internal and external disunity. God, however, is incapable of change, since He is Perfection. He is exactly Who He is, always has been, and will always be. This results in a divine simplicity and harmonious unity that is infinitely beyond His creation. God doesn’t need anything to exist because it is His very nature to exist as the unchanging, transcendent God.
Within this divine simplicity and perfect unity we can distinguish various attributes of God, noting that each attribute is perfectly united with the others in the most simple and complete way. God alone is all-powerful and has supreme authority over all creation. He alone perceives all potentiality within creation and within Himself. He is perfectly wise, just, and merciful. He is both completely beyond creation (transcendent) and intimately involved with every aspect of creation (immanent). God is the perfection of holiness and morality. He is the only standard of goodness and truth. He is present everywhere at all times—unchanging and eternal. God is Love.
This philosophically rich language attempts to describe God in His oneness—He is One God, not three Gods. The Father, Son, and Holy Spirit each share perfectly in the one divine nature, and all share the same divine attributes. To understand the profound mystery of the Trinity, we must start with the above oneness of God and then move into His threefold Personhood.
How can something be one and three at the same time? We know that God is one-in-three solely because this is the way the Scriptures reveal God to us. The Old Testament alluded to the threefold personhood of God, and Jesus explicitly identified the three persons as the Father, Son, and Holy Spirit. Without this revelation from our Lord, human reason alone could never arrive at the realization that God is One in Three.
In Sacred Scripture and Church teaching, God’s attributes and existence can be summed up as Love. “God is love” (1 John 4:8). Love cannot exist without a giver, a receiver, and the love that unites them. Hence, it is the very nature of God to love perfectly, to receive love perfectly, and to be love itself.
In the Trinity, the Father loves the Son, the Son loves the Father, and this mutual love is personified in the Holy Spirit. This “love” in God is defined by the Church as an “eternal begetting” and as an “eternal procession,” which are fundamentally different from an act of creation. The words “begetting” and “proceeding” are used to point to the relational origin of love. The Father eternally begets the Son, reflecting an eternal exchange of love. The Holy Spirit, then, proceeds from both the Father and the Son, emanating from their mutual love. These profound mysteries are articulated in the Nicene Creed:
I believe in one Lord Jesus Christ, the Only Begotten Son of God, born of the Father before all ages. God from God, Light from Light, true God from true God, begotten, not made, consubstantial with the Father; through him all things were made…I believe in the Holy Spirit, the Lord, the giver of life, who proceeds from the Father and the Son, who with the Father and the Son is adored and glorified, who has spoken through the prophets.
The formulation of the Trinitarian relationship in the Creed reveals the profound depth of God’s nature: God is of one essence, yet three distinct Persons. Each Person is involved in an eternal, loving relationship with the others. The mystery within this formulation requires contemplation, as it reveals a God Who is deeply relational and Whose very nature is to exist in a state of perfect, self-giving love.
