The Trinity is One. We do not confess three Gods, but one God in three persons,
the “consubstantial Trinity”
What does person mean in Holy Trinity?
From Father John Hardon’s Catholic Dictionary:
“PERSON. “An individual substance of a rational nature” (Boethius). Therefore every individual intellectual substance which is complete in itself, uncommunicable and existing for itself, is a person. Essential to person in theological terms are intelligence and substantiality, wholeness in oneself and especially individuality. From individuality flow such features of personhood as distinctiveness, incommunicability, and uniqueness. Among human persons there are also the elements of responsibility and possession of distinctive rights. (Etym. Latin persona, actor’s mask; character; supposition of a rational nature.)”
From the Catechism:
253 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.”
266 “Now this is the Catholic faith: We worship one God in the Trinity and the Trinity in unity, without either confusing the persons or dividing the substance; for the person of the Father is one, the Son’s is another, the Holy Spirit’s another; but the Godhead of the Father, Son and Holy Spirit is one, their glory equal, their majesty coeternal” (Athanasian Creed: DS 75; ND 16).
689 The One whom the Father has sent into our hearts, the Spirit of his Son, is truly God. Consubstantial with the Father and the Son, the Spirit is inseparable from them, in both the inner life of the Trinity and his gift of love for the world. In adoring the Holy Trinity, life-giving, consubstantial, and indivisible, the Church’s faith also professes the distinction of persons. When the Father sends his Word, he always sends his Breath. In their joint mission, the Son and the Holy Spirit are distinct but inseparable. To be sure, it is Christ who is seen, the visible image of the invisible God, but it is the Spirit who reveals him.
1812 The human virtues are rooted in the theological virtues, which adapt man’s faculties for participation in the divine nature: for the theological virtues relate directly to God. They dispose Christians to live in a relationship with the Holy Trinity. They have the One and Triune God for their origin, motive, and object.
IF IT STILL SEEMS UNCLEAR IT IS BECAUSE THIS IS THE MYSTERY OF ALL MYSTERIES; THEREFORE THE VERY BASIS FOR “FAITH.”
Traditionally this is a common theological explaination:
Father = Creator
Christ = redeemer and Savior
Holy Spirit = Sactifier; teacher; protector
