Definition
Restorationism is the theological position that God will ultimately restore and reconcile all people (and possibly all spiritual beings) to himself, but connects this restoration to a real process of judgment and chastening — thereby distinguishing itself from universalism. The punishment for sin is real but temporary and corrective in nature, not eternal and retributive without purpose. In this wiki the term functions as the house-style label for the dominant position in the corpus.
Usage in the Corpus
Stephen Jones
Jones makes the distinction between restorationism and universalism programmatic: “God is not like a judge who is forced to release everyone because the jury was wrong. He is more like a Father who disciplines his children until they learn what is right.” The universalism Jones critiques neglects judgment; restorationism acknowledges it. Christ saves as a righteous Judge who punishes and restores. Jones uses “Restoration of All Things” as his preferred term, derived from Acts 3:21. [Jones, The Restoration of All Things, Ch. 2]
Cees Noordzij
Noordzij approaches restorationism from creation theology: creation itself groans and waits for its liberation (Rom. 8:18-25). His restorationism is cosmic in scope — not just individuals but the entire cosmos is restored — and processual: apokatastasis is not a cosmic reset but an eschatological maturation.
Origin
“Restorationism” follows the standard English -ism pattern for theological positions. The Dutch restaurationisme is the equivalent and should never be confused with the non-existent English restoratianisme (a Dutchified anglicism that must be avoided in Dutch contexts).
