What's with the Trinity?

So I am preaching on the Trinity in the upcoming month and have been reading up in my books I have gathered over the years. Here are some valuable quotes when considering this intense doctrine:

"The Way God is revealed and experienced in history corresponds with the way in which God actually is" A.E. McGrath summarizing Karl Rahner

"The 'mystery of salvation' happens first; then we move on to formulate doctrines concerning it"

A.E. McGrath

Robert Jensen is not the most quotable guy but basically, The Title 'Father, Son, & Holy Spirit' is not just a means to understand the Trinity and his roles but revelations in scripture of who God is. His name is Father, Son & Holy Spirit.
