The Church not merely an invisible kingdom, but also a visible community. Fundamental importance of the community idea. The solidarity of mankind in sin and in redemption a basic conception of Christianity. The organism of the Church represents and enforces that solidarity. A unitary organism with inner differentiation of function. And possessing, of necessity, a visible expression of its unity, a visible head. Essential character of papal and episcopal authority Objections to it on the ground that it is inconsistent with our Lord’s teaching. In reality a service of the community in His name.

Chapter IV: Through the Church to Christ

The genesis of Catholic faith. Three cardinal points: God, Christ, the Church. The existence of God discernible by natural reason, but His love to be learnt only from revelation. Full faith in God attained by faith in Christ. How is faith in Christ attained? The apostles attained it preparatorily by His personal teaching, fulfillingly by the Pentecostal gift of the Holy Spirit. So we also: preparatorily by the teaching of His living, apostolic Church, fulfillingly by the operation of His grace. Not from lifeless records, but from the living witness of a living organism sustained and animated by Him, from immediate contact with Christ living in His Church. Christianity more than a system of thought: a living stream of divine life flowing out from Christ and bearing His truth and His life, pure and uncontaminated, down the centuries.

Chapter V: The Foundation of the Church in the Light of the Teaching of Jesus

Was the Church founded by Christ Himself, or is it the creation of His disciples? The objection, that our Lord’s attitude towards Jewish religion and ecclesiastical authority is inconsistent with His foundation of a Church, scientifically untenable. The objections of the eschatological school. Examination of our Lord’s teaching concerning the coming of the Kingdom and concerning the end of the world. Chronological misconceptions of some of His disciples. The plain teaching of His parables. The foundation of the Church in the direct line of His thought: a Church in gradual process towards perfection and ever ordinated towards a supernatural and other-worldly goal.

Chapter VI: The Church and Peter

Special position of St. Peter among the twelve attested not only by the history of the primitive community, but by the witness of St. Paul. Unsatisfactory theories advanced in explanation of this pre-eminence. The all-sufficient explanation to be found in Matthew XVI, 13-19. This passage no Roman forgery or anti-Pauline interpolation. Significance of its details, especially of Simon’s new name with its immediate and universal success. Certain that he was given a special authority by Christ Himself. But does this appertain to his successors? The divine intentions of our Lord, the witness of history. The Church based on Peter the only guardian of genuine faith in Christ and the only hope for our civilization.

Chapter VII: The Communion of Saints
