You mention the antidepressants in relation to him not believing that Jesus is God.. would you see that as a connection?
Does he not believe that Jesus is the Son of God?
I'm pretty sure this is a matter of Creed. Starting with the Churches beliefs and likely the pastors "reading the Bible" with an Arian interpretation.
Godhead[edit]
The UPCI adheres to a "oneness" concept of the Godhead, in contrast to
orthodox belief in the
Trinity. Hence, an understanding of Oneness doctrine over against Trinitarian doctrine is critical in any analysis of UPCI beliefs.
The
Christian doctrine of the
Trinity defines
God as three consubstantial
persons,
[6] or
hypostases[7]—the
Father, the
Son (
Jesus Christ), and the
Holy Spirit; "one God in three persons". The three
persons are distinct, yet are one "substance, essence or nature".
[8] In this context, a "nature" is
what one is, while a "person" is
who one is.
[9][10][11]
Oneness believers, by contrast, hold that God is absolutely and indivisibly one. (Deuteronomy 6:4) This verse, as oneness believers believe, confirms that there is NO TRINITY, the Lord is one. They also affirm that in Jesus dwells all the fullness of the Godhead bodily and that Jesus is the only name given for salvation (Colossians 2:9). The
Father was revealed to the world in the name of Jesus, the Son was given the name of Jesus at birth, and the Holy Spirit comes to believers in the name of Jesus. Thus they believe the apostles correctly fulfilled Christ's command to baptize “in the name [singular] of the Father, and of the Son, and of the Holy Ghost” by baptizing all converts with the invocation of the name of Jesus (Matthew 28:19; Acts 2:38; 8:16; 10:48; 19:5; 22:16).
[12]
Oneness believers affirm that God has revealed Himself as Father (in parental relationship to humanity), in the Son (in human flesh), and as the Holy Spirit (in spiritual action). They acknowledge that the one God existed as Father, Word, and Holy Spirit before His incarnation as Jesus Christ, the Son of God; and that while Jesus walked on earth as God Himself incarnate, the Spirit of God continued to be omnipresent.

Some of the pastor's statements actually seem to contradict the official non-Trinitarian theology of that Church in the direction of the Arian heresy... or even a form of Adoptionism.
