Dan Dean’s church web site puts it like this:
...there is One True God that has manifested Himself as Father in creation, Son in redemption and the Holy Spirit in emanation. (Deuteronomy 6:4; I Timothy 3:16; Acts 2:33)[10]
PCD is willing to use words like “Triune” of God, but only in the sense that God has three different roles that he performs throughout Scripture; three different manifestations. This is a key concept that differentiates PCD’s god from the God of the Bible. Although this god manifests Himself in these three roles of Father, Son, and Holy Spirit, these manifestations are not eternal, but temporary. Additionally, there are no relationships of a personal kind between the Father, the Son, and the Holy Spirit.
This is demonstrated most clearly in The Enquirer’s Handbook, a book of basic doctrines published by Randy Phillips’ ministry, The World of Pentecost. The Handbook is perhaps the most detailed theological statement available from the ministries of Randy Phillips, Shawn Craig and Dan Dean.

The Enquirer’s Handbook denies that the Father, Son, and Spirit are personal centers of identity, capable of relationship with each other. Instead, it claims that the terms “Father,” “Son,” and “Holy Spirit” are merely descriptive of the ways that the unipersonal God acts.
In other words, God appeared in the flesh (as a son)…The Father, Son, and Holy Ghost are simply three manifestations of One God. You, yourself, may be manifested as a son to your father, a husband to your wife, and a father to your children. As an individual person you may be manifested in various ways; and likewise the Almighty God is manifested as a Father, a Son, and a Holy Ghost while He remains indisputably, undeniably, ONE.[12]
