This document discusses the Catholic doctrine of papal infallibility according to Church fathers, scripture, and tradition. It provides scriptural evidence from the New Testament showing Jesus protecting Peter and the Church from error. It also cites passages from the Old Testament prophesying that the Church would be "a Holy Way, free from error." Additionally, it references statements from early Church fathers like Irenaeus, Cyprian, and Athanasius affirming the infallibility and inerrancy of the Church. The document concludes by questioning how unlikely it would be for all churches to have fallen into the same errors.
