#9 The Trinity

Who is God?

This is the most fundamental question for any believer who feels God’s presence but does not comprehend the Being who is felt, the One who calls.

The vision of Thomas Aquinas is truly sublime.  It is he who consolidated the Christian concept of God as Trinity.

This post is longer as it contains the most important part of this article.

This is what Thomas Aquinas writes in Summa Theologica Volume 1: Treatise on the Most Holy Trinity (I will not quote page numbers too much as they will be different in different editions).

God is one essence and three persons.  The divine persons are distinguished as each subsists distinctly from the others in the divine nature.  There is only one essence though and one Godhead.

God the Father is existence itself, the principle without principle.  The Father is the principle of the whole deity.  It is the property of the Father to beget the Son.  God is the Father of the Son from eternity.

Jesus, the Son is begotten of God the Father receiving the whole Godhead from God.

Jesus is the principle from a principle.  He is wisdom.

Jesus is the image of the invisible God.

The Holy Spirit is the spirit of Jesus.

The Holy Ghost proceeds from Father and Son.  He is not made, nor created, nor begotten, but proceeding.  There is unity between Father and Son by the Holy Spirit.

The Father, Son and Holy Spirit have the essence of God which is existence; which is perfection; which is the goal of all things.

Power belongs to the Father who is the principle of the whole Godhead.  Wisdom belongs to the Son as the Word.  Goodness whose object is love has the likeness of the Holy Spirit.

The Father and Son are in everything one and are one principle of the Holy Spirit.  The Father in begetting the Son communicated His whole nature to Him.  “The Son was not begotten from nothing, but from the Father’s substance.” 

Creatures were originally created from nothing.  The principle of each ‘genus’ or type of creature made came from the over-arching principle of God.  It’s form was originally established by God it’s maker.

Humans are different from all other creatures in that God, the Holy Spirit may be given to us through grace and reside in our souls.  We can begin to know the One who made us.
