Are the biblical feasts only part of Israel’s past, or do they still matter for the church today? And has “replacement theology” (the idea that the church has taken Israel’s place) quietly shaped how Christians read those feasts and the Bible itself? Biblical Feasts and Supersessionism: A Biblical and Historical Study Critiquing Replacement Theology tackles these questions head‑on. This rigorous yet accessible study brings together three threads that are rarely woven carefully: the biblical feasts , supersessionism (replacement theology) , and the ongoing relationship between Israel and the church . Rooted in close exegesis of the King James Version (KJV) and informed by both classic and recent scholarship, this book: Explores Leviticus 23 in depth, showing how Passover, Unleavened Bread, Firstfruits, Pentecost (Weeks), Trumpets, the Day of Atonement, and Tabernacles are presented as “the feasts of the LORD” and “holy convocations,” not merely “Jewish holidays.” - Traces how Jesus, the apostles, and the early Jewish believers related to the biblical feasts, from Passover and Tabernacles in the Gospels to Pentecost in Acts. - Explains and evaluates the three main forms of supersessionism / replacement theology (punitive, economic, and structural), showing how each has affected Christian views of Israel and the feasts. - Surveys how church history – from the early church fathers through the Reformation and into modern theology – often sidelined Israel and God’s appointed times, sometimes with deeply harmful consequences for Jewish‑Christian relations. - Introduces post‑supersessionist and Messianic Jewish perspectives that affirm God’s ongoing purposes for Israel while fully confessing Jesus as Messiah, and that see the biblical feasts as theologically rich for all believers, even if observed differently under the new covenant. - Offers a constructive, post‑supersessionist reading of the feasts , arguing that God remains faithful to His covenant with Israel, that the church (Jews and Gentiles in Messiah) is grafted into Israel’s story rather than replacing it (Romans 11), and that the feasts still point to Christ and God’s purposes for history. This is not a call to legalism, nor a Hebrew Roots manifesto. It is a careful biblical and historical study that: Critiques replacement theology without attacking individuals or denominations. - Distinguishes serious theological critique from anti‑Jewish caricature. - Encourages Christians to rediscover the biblical feasts as “appointed times” that reveal God’s redemptive plan — past, present, and future. If you are a pastor, Bible teacher, seminary student, or thoughtful believer wrestling with questions like: Has the church replaced Israel? - What is supersessionism, really? - How should Christians view Israel, the church, and the feasts of the LORD? - Are Passover, Pentecost, Trumpets, Atonement, and Tabernacles still relevant under the new covenant? This book is written for you. With clear structure, KJV‑based exegesis, and respect for both Scripture and the Jewish people who have preserved it, Biblical Feasts and Supersessionism invites you into a deeper understanding of God’s appointed times, Israel’s enduring role, and the fullness of redemption in Christ. Read it slowly, with an open Bible, and with the humility to let God’s faithfulness to His covenants reshape how you see Israel, the church, and the feasts of the LORD.
