How sublime and consoling is the thought that whithersoever a Catholic goes over the broad world, whether he enters his Church in Pekin or in Melbourne, in London, or Dublin, or Paris, or Rome, or New York, or San Francisco, he is sure to hear the self-same doctrine preached, to assist at the same sacrifice, and to partake of the same sacraments.
This is not all. Her Creed is now identical with what it was in past ages. The same Gospel of peace that Jesus Christ preached on the Mount; the same doctrine that St. Peter preached at Antioch and Rome; St. Paul at Ephesus; St. John Chrysostom at Constantinople; St. Augustine in Hippo; St. Ambrose in Milan; St. Remigius in France; St. Boniface in Germany; St. Athanasius in Alexandria; the same doctrine that St. Patrick introduced into Ireland; that St. Augustine brought into England, and St. Pelagius into Scotland, and that Columbus brought to this American Continent, and this is the doctrine that is ever preached in the Catholic Church throughout the globe, from January till December--"Jesus Christ yesterday, and today, and the same forever."(28)
The same admirable unity that exists in matters of faith is also established in the government of the Church. All the members of the vast body of Catholic Christians are as intimately united to one visible Chief as the members of the human body are joined to the head. The faithful of each Parish are subject to their immediate Pastor. Each Pastor is subordinate to his Bishop, and each Bishop of Christendom acknowledges the jurisdiction of the Bishop of Rome, the successor of St. Peter, and Head of the Catholic Church.
But it may be asked, is not this unity of faith impaired by those doctrinal definitions which the Church has promulgated from time to time? We answer: No new dogma, unknown to the Apostles, not contained in the primitive Christian revelation, can be admitted. (John xiv. 26; xv. 15; xvi. 13.) For the Apostles received the whole deposit of God's word, according to the promise of our Lord: "When He shall come, the Spirit of truth, He shall teach you all truth." And so the Church proposes the doctrines of faith, such as came from the lips of Christ, and as the Holy Spirit taught them to the Apostles at the birth of the Christian law--doctrines which know neither variation nor decay.
