Holy Spirit

Christadelphians reject the mainstream Christian teaching that the Holy Spirit is a distinct third person of the Godhead. In their understanding, the Holy Spirit is the power, energy, or influence that proceeds from God the Father — the means by which God accomplishes his purposes in creation, prophecy, inspiration, and the life of believers. The Spirit is God's arm extended, not a separate divine being.

In the New Testament, Christadelphians read references to the Spirit being 'given,' 'poured out,' or 'dwelling in' believers as descriptions of God's power at work in human beings — not as a divine person taking up residence. The gifts of the Spirit described in the early church (prophecy, healing, tongues) are understood as miraculous abilities directly granted by God through his power during the apostolic period, now ceased. The Spirit's work in believers today is through the Word of God rather than through direct supernatural experience.

This pneumatology is consistent with the Christadelphian rejection of Trinitarian theology: if God is strictly one person (the Father), and the Holy Spirit is his power rather than a separate person, then no Trinity is possible. Christadelphians regard the personification of the Spirit in certain biblical texts as a literary device (as one personifies wisdom or justice) rather than evidence of a distinct divine person.
