UPCI pastor Jacob Ponzi vs Kelly Powers debate which is biblical the Trinity or Oneness? This will be a friendly debate discussion on what is the Trinity doctrine and what is Oneness theology, and which is biblical? Does the Bible teach there is one God revealed through 3 distinct persons as the Father, the Son (Jesus Christ), and the Holy Spirit? Or does the Bible teach there is one God manifested in three modes/forms as the Father, the Son (Jesus Christ), and the Holy Spirit?
