Hebrews never pits the covenants against one another as law versus gospel; it presents them as grace and grace—the same house, the same people, the same promise. Yet the old was always preparatory: shadow giving way to substance, promise to fulfillment. Marcus A. Mininger traces that organic development and shows why the unity of the one covenant is precisely what makes Hebrews’ warning so urgent. The address closes where the letter does—on persevering within the covenant and resting in the sole sufficiency of Christ.
Dr. Marcus A. Mininger is professor of New Testament at Mid-America Reformed Seminary, with research on Paul and the General Epistles—including a forthcoming study of the warning passages in Hebrews.
Delivered at the 2026 Reformed Forum Theology Conference, “The Covenant of Grace: One Savior, One People, One Purpose,” at Lakeland Church in Gurnee, Illinois, on September 26, 2026.

Few passages have unsettled readers like Hebrews’ warning that it is “impossible … to restore again to repentance” those who fall away. Does it teach a sin beyond forgiveness? Marcus A. Mininger clears away the common misreadings and names the real danger the author confronts: the temptation to abandon Christ and re-lay a foundation in the old covenant alone. The warning, rightly heard, is not about a sin too great to forgive but about the impossibility of going back—and it sets up the covenant question taken up in the session that follows.

A greater Joshua has come. Benjamin L. Gladd takes another look at Jesus’s exorcisms, reading them against the Old Testament backdrop of Israel’s conquest. Where Joshua led a people into an earthly rest by the sword, Christ leads his people into a greater rest by the Spirit and the word, defeating the powers that held them captive. The kingdom does not advance by force but by the triumph of the one Savior who gathers one people to himself, and the exorcisms are a preview of that greater conquest.
Dr. Benjamin L. Gladd is executive director of the Carson Center for Theological Renewal and formerly professor of New Testament at Reformed Theological Seminary, Jackson. He edits the Essential Studies in Biblical Theology series and has written widely on the use of the Old Testament in the New, including works co-authored with G. K. Beale.

When does the long-promised restoration of Israel take place? G. K. Beale gives particular attention to Acts 1:8 and its use of the Old Testament and argues that the restoration is already under way in the church's Spirit-empowered witness to the nations. God fulfills his covenant promises to Israel in Christ and carries them to the ends of the earth, as the one Savior gathers one people to himself. The answer has direct consequences for how we understand the church, the nations, and the promises of the covenant.
Dr. Gregory K. Beale teaches at Reformed Theological Seminary, Dallas. He is a leading New Testament scholar known for his work on biblical theology, the use of the Old Testament in the New, and the temple theme across Scripture.

Mark Gilbert joins Camden Bucey to examine what Protestants and Roman Catholics mean when they speak of Christian unity. Drawing on Gilbert’s conversion from Roman Catholicism, they contrast a unity grounded in the Spirit’s work through the Word with Rome’s institutional claim to mediate grace and gather humanity into one visible communion.
The conversation turns to Vatican II and Karl Rahner’s doctrine of the “anonymous Christian.” Camden and Mark consider Rahner’s anthropology, his account of God’s self-communication, and the influence of this framework on Roman Catholic inclusivism. They conclude with a pastoral call to speak with clarity and charity and to offer the assurance found only in the finished work of Christ.
