Vindication of the Animadversions on Fiat Lux

A rigorous defense of Protestant Christianity against Roman Catholic polemics, written in response to *Fiat Lux* and its epistolary reply. Owen dismantles Romanist arguments for papal supremacy, infallibility, and the sole authority of Rome to settle religious controversy. He examines key doctrinal flashpoints — the Mass, image worship, transubstantiation, and the rule of faith — exposing contradictions in Catholic tradition while grounding Protestant unity in Scripture and the early Church Fathers. A masterwork of 17th-century Reformed apologetics.
