I posted two scriptures as representative examples. There are certainly more that prove the point....much more so than any points about the modern trinity theory. We can even extend that into the natural world...2 sexes....2 people make 1....two halves of the body make one....etc etc.
The scriptures you posted and may post will reflect that The Father, Jesus and the Holy Spirit are each unique Persons. The doctrine of the trinity affirms this.
It just further affirms that they are all God and yet God is one, which is a mystery, but undeniable.
The father is given the attributes of God. Jesus is given the attributes of God. The Holy Spirit is given the attributes of God. We are baptized into the name of the Father, Son and Holy Spirit for this reason as He directs. How blasphemous if we were baptized in the name of someone not God!
We are made in God’s image. We are a trinity ourselves -— body, soul (the mind and emotions), and spirit (the part of us that is alive unto God).
