Trinitarianism, Oneness theology, Unitarianism, and Pentecostalism represent distinct theological frameworks, but none of them are denominations in themselves. Trinitarianism, grounded in philosophical reasoning, is a widely accepted doctrine across most mainstream Christian traditions. Oneness theology, rooted in Modalism, emphasizes the singularity of God's person but is also not a denomination. Unitarianism, in contrast, rejects the Trinity and affirms that God is solely the Father.
From my own personal experience, I have found that I agree with the Unitarian view that the Father alone is the one true God, and I cannot align myself with either Oneness theology or the doctrine of the Trinity. However, my experience with Pentecostalism has added complexity to my beliefs. Though I hold a Unitarian view of God, I have truly experienced the reality of the Pentecostal experience. When Pentecostal missionaries laid hands on me, I personally encountered the Holy Spirit in a profound and visible way—through manifestations such as prophesying and miraculous signs that affirmed the Spirit’s presence. This experience convinced me of the authenticity and truth of Pentecostal teachings, even though I do not share the same doctrinal stance on the nature of God.
Despite the personal experiences of many like myself, most Pentecostal churches still insist on belief in either the Trinitarian or Oneness view of God, which I find limiting. Unitarianism, while deeply meaningful in its affirmation of the Father alone as God, often overlooks the Pentecostal understanding of the Holy Spirit as a distinct person from the Father. Perhaps, just as I have come to appreciate both the Unitarian understanding of God and the Pentecostal experience of the Spirit, there is room for a greater understanding between these perspectives—an acknowledgment that personal experience of the Holy Spirit can transcend theological differences.
