Doesn't sound like it's from Scripture
Simple faith is lasting faith. The most spiritual people I know are simple -- they don't concern themselves with a Trinity of persons or three gods. They worship Jesus Christ in all His Glory and Dominion.
Following the mind of Christ, we are led to consider the Father and the Holy Spirit, all one with Him, but perhaps your faith through Him is focused elsewhere, assuming it doesn't alter in His faith to the Father.
De Re/De Dicto and the dcotrine of Kenosis are well developed doctrines within the Catholic Church and time tested in Faith. You might find them worthy to consider in your studies.
