I Spiritual Fatherhood
1 Trinitarian Nature of God, uniquely Christian
= The mystery of one God in three Persons: Father, Son, and Holy Spirit. The revealed truth of the Holy Trinity is at the very root of the Church’s living faith as expressed in the Creed (symbolon, 12 articles). The mystery of the Trinity in itself is inaccessible to the human mind and is the object of faith only because it was revealed by Jesus Christ, the divine Son of the eternal Father.
232 Christians are baptized “in the name of the Father and of the Son and of the Holy Spirit” Before receiving the sacrament, they respond to a three-part question when asked to confess the Father, the Son and the Spirit: “I do.” “The faith of all Christians rests on the Trinity.”
233 Christians are baptized in the name of the Father and of the Son and of the Holy Spirit: not in their names, for there is only one God, the almighty Father, his only Son and the Holy Spirit: the Most Holy Trinity.
234 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”.
2 Jesus and the Father are One
262 The Incarnation of God’s Son reveals that God is the eternal Father and that the Son is consubstantial with the Father, which means that, in the Father and with the Father the Son is one and the same God. [Faith dependent on proper use of prepositions.]
Prologue of John1:1-5
In the beginning was the Word, and the Word was with God, and the Word was God.2 He was in the beginning with God; 3 all things were made through him, and without him was not anything made that was made. 4 In him was life, and the life was the light of men. 5 The light shines in the darkness, and the darkness has not overcome it.
The Catechism expounds on this text following the reflection of the Church for 2,000 years.
The dogma of the Holy Trinity follows on this Scripture
Worth reading so much from CCC because it is very easy to get the Trinity wrong.
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.”84 In the words of the Fourth Lateran Council (1215), “Each of the persons is that supreme reality, viz., the divine substance, essence or nature.”
254 The divine persons are really distinct from one another. “God is one but not solitary.” “Father”, “Son”, “Holy Spirit” are not simply names [nominalism] 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.
255 The divine persons are relative to one another. Because it does not divide the divine unity, the real distinction of the persons from one another resides solely in the relationships which relate them to one another: “In the relational names of the persons the Father is related to the Son, the Son to the Father, and the Holy Spirit to both. While they are called three persons in view of their relations, we believe in one nature or substance.” Indeed “everything (in them) is one where there is no opposition of relationship.” “Because of that unity the Father is wholly in the Son and wholly in the Holy Spirit; the Son is wholly in the Father and wholly in the Holy Spirit; the Holy Spirit is wholly in the Father and wholly in the Son.”
Nature & person, nature what is proper to tht being. Proper to ‘Godness’ is unity. Impossible any being nature of God to not be one. Nature of angels impossible to be corporeal, spiritual essence. Human must be form & matter, true to our nature.
All of natures, there is no conflict in man, angel there are many of them.
Oneness is part of nature of God, Boethius. Man= Substance of rational nature.
