Galations 1:
1. Paul an apostle--not from men nor through man, but through Jesus Christ and God the Father, who raised him from the dead-
Romans 8:
11. If the Spirit of him who raised Jesus from the dead dwells in you, he who raised Christ Jesus from the dead will give life to your mortal bodies also through his Spirit which dwells in you.
1 John 2:
19. They went out from us, but they were not of us; for if they had been of us, they would have continued with us; but they went out, that it might be plain that they all are not of us.
How is it made manifest?
It's John 2:19, not 1 John 2:19.
In these three examples we have the the Father, the Spirit and Christ Himself raising Himself.
However, one will not find much trinitarian in St. Paul's wiritngs. In fact even in Romans 8 where he mentions the Spirit of God, he is using the term distinctly in the OT manner as power of God and not a distinct Hypostasis.
One will nto arirve at any trinitarian forumla by focusing on St. Paul.
