Biblical Inerrancy in Catholic Dogma and Tradition
The Catholic Church affirms biblical inerrancy, but defines it differently than many Protestant traditions, particularly those shaped by the Old Princeton theology of the late 19th and early 20th centuries. The disagreement centers not on whether Scripture is trustworthy, but on what "inerrancy" means and how Scripture relates to the broader deposit of faith.
The Catholic Position
Catholic teaching holds that Scripture is without error in what it affirms for the sake of our salvation. The Catechism of the Catholic Church states that the Church "does not derive her certainty about all revealed truths from the holy Scriptures alone. Both Scripture and Tradition must be accepted and honoured with equal sentiments of devotion" [6]. This reflects the Catholic understanding that divine revelation comes through two channels—Scripture and Sacred Tradition—both transmitted through the apostolic succession and interpreted by the Magisterium. Inerrancy, in this framework, applies to Scripture's teaching on faith and morals, not necessarily to incidental historical or scientific details. The Church's certainty rests on the combined witness of Scripture, Tradition, and the teaching authority entrusted to the apostles' successors [6].
The Reformed Protestant Position
Reformed theology, particularly in its confessional expressions, typically affirms plenary verbal inerrancy: Scripture is without error in all its affirmations, including historical and scientific matters, because God "does not lie" [3]. This position emphasizes sola scriptura—Scripture as the sole infallible rule of faith. Calvin and other Reformers insisted on Scripture's self-authenticating authority, independent of ecclesiastical validation. The foundation of faith "standeth sure" precisely because it rests on God's unchangeable character [1], and the Son of God preached in Scripture "is made yea in Him," confirmed and unchangeable [2]. For this tradition, any limitation of inerrancy to "salvific" matters undermines Scripture's full authority.
Shared Ground and Divergence
Both traditions affirm that God cannot lie [3] and that divine truth is permanent [4, 7]. The divergence stems from differing views on the locus of interpretive authority. Catholics locate it in the Church's living Magisterium alongside Scripture; Reformed Protestants locate it in Scripture alone, interpreted by the Spirit-illumined community. Cyprian's dictum that "custom without truth is the antiquity of error" [5] has been claimed by both sides—Catholics to defend doctrinal development under Tradition, Protestants to challenge traditions not grounded in Scripture.
