…Protestants, especially fundamentalists, object that they consider “Scripture alone” to be the “infallible” authority within the Church. And Catholics are obliged to agree that Scripture contains, at least materially, all the truth God willed to reveal to us. But both history and logic confirm Pontificator’s Second Law: “When the Bible alone is our authority, the Bible ceases to be our authority.” That is why Protestant modernism arose; Protestant fundamentalism was merely the reaction of those with residual faith against that consequence. But such fundamentalism remains intellectually powerless against it.
