The Apostle's Creed: 1. The Evaluation 2. The Effect 3. The Enjoyment The sermon, reflecting on the 75th anniversary of the Free Presbyterian Church of Ulster, centers on Acts 2:42, emphasizing that the church's enduring identity and spiritual vitality rest on steadfast adherence to the apostles' doctrine—expository, exclusive, and evangelistic in nature. This doctrine, rooted in Scripture and focused solely on Christ, is not a static relic but a living, transformative truth that continually reforms believers and the church by the Holy Spirit. The sermon underscores that true doctrine produces biblical fellowship, necessitates separation from error and compromise, and culminates in the joyful, intimate enjoyment of union with Christ through worship and the Lord's Supper. Drawing from historical examples, including the Reformation and the founding of the denomination, it calls the church to remain faithful to the unchanging Word, rejecting misuses of the phrase 'always reforming' that justify doctrinal compromise, and instead embracing the biblical imperative to be continually reformed by Scripture alone.
