Person here from that Catholic creed is translated from persona which can mean some sort of mask. For me, Jehovah being the Lord Jesus' soul and the Holy spirit being the Lord's proceeding (action) makes a whole lot more sense. We are in the image and likeness of God. I can relate to that.
Isaiah 49:11 For My own sake, for My own sake, I will do it; For how should My name be profaned? And I will not give My glory to another. God’s Ancient Plan to Redeem Israel 12 “Listen to Me, O Jacob, And Israel, My called: I am He, I am the First, I am also the Last.
From the Bible Study in the original post, it is explained how the infinite and finite coexisted within Jesus up until his death and Glorification (whereby he became fully infinite and un-created - 'One with the Father', but He also claims that during His lifetime, in Scripture). That's what makes sense to me.
As an aside, in the Bible: Jehovah means the Lord in respect to Divine good, while God means the Lord in respect to Divine truth.
A recent article on this is at: The true one-ness of the Trinity
HMMMmmm...
What's up with this BINARY seen here???
Genesis 1:26
Then God said, "Let us make mankind in our image, in our likeness, so that they may rule over the fish in the sea and the birds in the sky, over the livestock and all the wild animals, and over all the creatures that move along the ground."
That is not the meaning of "person" that I used, and obviously the Nicene Christians did not consider Christ to be merely a "mask." They were fighting against the Arians. You would be better off not taking Swedenborgian definitions and imposing them on the scripture.
The word "person" doesn't actually occur in the creed, but the word the fathers used in Greek is either /prosopon/ or /hypostasis/. The word prosopon can mean mask, or just face, or the visible outward manifestation of a being.
This is contrasted with "ousia," which is the underlying deeper reality or nature.
The doctrine of the Trinity is simply that God is one ousia and three hypostases/prosopa. Father, Son, and Holy Spirit are each totally God from all eternity, but they are still distinct in their personhood. The Athanasian creed said that the Father is God, the Son is God, and the Holy Spirit is God, but there are not three gods but one God. The Father is not the Son, the Son is not the Spirit, and the Spirit is not the Father.
God is therefore One, and is at the same time an eternal community of perfect love.
