Note that at 2:27 of the Ephesians video the narrator refers to God as Father, Son, and Spirit. This video is a third-party resource,  not produced by the UPCI or its affiliates.

As Oneness Pentecostals, we attest that while God interacts with mankind as Father, Son, and Spirit, these facets do not reflect God as separate persons in the Godhead, and in no way diminish His indivisible singularity.
