Private-Spirit
Each believer's immediate Spirit-illumination decides the meaning of Scripture without ecclesial regulation — the radical position.
This is a contested or rejected alternative.
The Westminster baseline on Interpretation is Scripture-Interprets-Scripture. Personas and schools listed below hold this alternative position instead — either because they argued for it at the Assembly (like the Erastians on polity) or because they represent a receiving tradition that departed from the Standards on this point.
Other positions on Interpretation
Scripture-Interprets-Scripture WCF
The infallible rule of interpretation is Scripture itself: when there is a question about the true sense of any passage, it must be searched and known by other places that speak more clearly (WCF I.9).
Church-Magisterium
Authoritative interpretation belongs to the church's teaching office — the Roman position rejected by WCF I.10.
Critical-Reason
Scripture is interpreted under the rule of autonomous human reason — the rationalist tendency.
