his article series on the sacraments is written from a genuinely ecumenical perspective, addressing the faith and practice of the worldwide Christian church across time and tradition. The series examines the sacraments as ordinances instituted by Christ and received by the church as visible signs of God’s saving work, with particular attention given to how they were understood, practiced, and articulated by the early church fathers. By tracing the historical development of sacramental theology, from the apostolic era through the patristic period and into later denominational expressions, the articles explore how Christian communities sought to remain faithful to Scripture while responding to cultural, pastoral, and theological challenges. Various sacramental views are presented carefully and respectfully, showing where they align with the biblical witness and where historical developments introduced interpretations that require critical evaluation. The purpose of the series is not to flatten doctrinal differences, but to promote clarity, unity, and discernment by grounding sacramental theology in Scripture, informed by the testimony of the early church and the unfolding history of Christian thought.
