The Holy Spirit Leads the Church in All Truth
He did not promise that the Holy Spirit would teach each individual separately. If every individual were under the guidance of the Holy Spirit, all who read Scripture sincerely should come to the same conclusion. But they do not. The frightful chaos as to the meaning of Scripture is proof positive that the Holy Spirit has not chosen this way of leading men to the truth. It is blasphemy to say that the Holy Spirit does not know His own mind, and that He deliberately leads men into contradictory notions. Christ promised to preserve His Church as a Church by the guidance of the Holy Spirit, and the only Church which shows signs of having been preserved is the consistent Catholic Church. The individual is guided by the Holy Spirit to a certain extent in the ways of holiness, but in the knowledge of revealed truth he is to be guided by the Catholic Church which Christ sent to teach all nations.
