The COGC holds that the Holy Spirit is the power and active presence of God — not a distinct third person of a Trinity. The Spirit is the means by which God acts in creation, inspires Scripture, regenerates believers, and empowers the church. This pneumatology is consistent with the COGC's strict monotheism: if there is only one God (the Father), then the Spirit is that one God's power at work, not an additional divine person.

The COGC's non-personal understanding of the Holy Spirit does not diminish its practical theology of Spirit-life. The Spirit genuinely transforms believers, produces fruit (Galatians 5:22-23), and enables Christian living and ministry. The disagreement with Trinitarian Christianity is about the ontological status of the Spirit (person vs. divine power), not about whether the Spirit is real and active.

The COGC is not a charismatic or Pentecostal community. It does not teach that speaking in tongues is evidence of Spirit baptism or that miraculous gifts continue today in the form described in Acts 2. The Spirit's ongoing work is primarily understood as illumination of Scripture, regeneration of believers, and the formation of Christlike character — not as dramatic supernatural manifestations.
