The RCA affirms sola scriptura—Scripture is the supreme authority—but maintains a more open posture toward spiritual gifts than strictly cessationist churches. While the RCA has historically affirmed that apostolic sign gifts ceased, contemporary RCA theology permits more openness to the Holy Spirit's ongoing work through spiritual gifts.

The RCA values tradition alongside Scripture, recognizing that the Three Forms of Unity represent the church's faithful interpretation of Scripture over time. While tradition is always subordinate to Scripture, it is not irrelevant. This reflects the Reformed heritage that values the church's historical wisdom while maintaining biblical authority.

Some RCA congregations have become more receptive to contemporary expressions of the Holy Spirit (prayer, healing, prophecy in various forms), while others maintain a more cessationist stance. The denomination does not require a single position but encourages discernment in evaluating charismatic claims against Scripture.
