The Free Will Baptist denomination includes Mark 16:9-20 (the Longer Ending) in its biblical canon and affirms these verses as authoritative Scripture. While the denomination may be aware of textual scholarship regarding the manuscript status of these verses, the Longer Ending is recognized as part of the biblical canon and is used in Free Will Baptist worship, teaching, and ministry.

The content of the longer ending—Christ's resurrection appearances, the commission to preach the gospel to all creation, signs following believers, and the ascension—aligns with Free Will Baptist conviction regarding evangelism and the resurrection. The passage supports the denomination's emphasis on universal gospel proclamation and the believer's witness to Christ.

Free Will Baptist practice treats these verses with full canonical authority. The longer ending is read in worship services, quoted in sermons, and cited in doctrinal teaching. The resurrection of Christ and the Great Commission are themes central to Free Will Baptist identity and mission.
