The Church of the Nazarene holds that the biblical canon is closed and that no new inspired writings supplement the Bible as an authoritative rule of faith. Scripture is the supreme and final norm. At the same time, the Wesleyan tradition affirms the ongoing work of the Holy Spirit in guiding believers and the church — a role that goes beyond simply 'applying' pre-existing Scripture but includes genuine spiritual guidance and illumination.

Wesley's own appeal to experience as a theological source (alongside Scripture, tradition, and reason) reflects the Wesleyan-Nazarene conviction that the Spirit continues to work in and through human experience. This does not mean that personal experience or visions produce new doctrine, but it does mean that the Spirit's work is experientially real and not merely cognitive or propositional.

The Church of the Nazarene is cautious about charismatic excesses and does not teach that ongoing prophecy or tongues-speaking constitutes authoritative revelation alongside Scripture. The denomination's emphasis is on the transforming work of the Spirit in entire sanctification — which is an experiential reality — rather than on dramatic prophetic or miraculous manifestations as primary vehicles of divine communication.
