You non-Trinitarians are good at avoiding direct questions.
God is spirit so why does a spirit have a spirit?
Why does John refer to the 7 spirits of God in Revelation 3?
How can a mode or manifestation be included in "us" unless there is more than one entity?
Why do the NT authors refer to God as Father and not Jesus? (this one is for hisway)
Why do the NT authors split the duties of the Father, the Son, and the Holy Spirit?
And, hisway, why do many Oneness Pentecostals believe once saved they are in fact sinless and never sin?
