For one "Many other signs also did Jesus in the sight of his disciples, which are not written in this book. " [John 20, 30]
"Therefore, brethren, stand fast; and hold the traditions which you have learned, whether by word, or by our epistle." (2 Thessalonians 2:14)
"The Lord Jesus shall be revealed from Heaven, with the angels of His power: in a flame of fire, giving vengeance to them who know not God, and who obey not the gospel of our Lord Jesus Christ." (2 Thessalonians 1:7-8)
"Whosoever revolteth, and continueth not in the doctrine of Christ, hath not God. He that continueth in the doctrine, the same hath both the Father and the Son." (2 John 1:9)
The principle of “the Bible alone as the sole rule of Faith”, cannot be a true principle of Christianity because it has no basis in the history of Christianity.
How did the early Christians learn their Faith?
How was the Faith communicated to them?
How did Our Lord tell the Apostles to communicate the Faith, the truths which must be believed for salvation?
He commanded them, “go forth and teach all nations, baptizing them in the Name of the Father and of the Son and of the Holy Ghost”. He said to Peter, “Thou art Peter and upon this rock I will build My Church” (Matt. 16:18). And Saint Paul taught clearly that it is the Church that is the pillar and mainstay of truth (I Tim. 3:16).
Our Lord gave to Peter authority, and He commissioned the Apostles to preach in His name. “As the Father hath sent Me, I also send you” (John 20:21).
Our Lord wrote no books. Nor did He say to His Apostles: “Sit down and write Bibles and scatter them over the earth, and let every man read his Bible and judge for himself”, which is the essence of Protestantism — each individual reads the Bible and decides for himself what are the truths of Christianity. No! As I said, Our Lord established a Church to teach in His Name: “He that heareth you heareth Me, he that despiseth you, despiseth Me” (Luke 10:16). “And if he will not hear the Church, let him be to thee as the heathen and the publican” (Matt. 18:17).
The Church and the Faith existed before the New Testament. Only five out of the twelve Apostles wrote anything down at all! The Church was teaching and administering the Sacraments, the Apostles were forgiving sins, the Church was making martyrs for seven to ten years before one jot of the New Testament was set down on parchment.
The Church was spread throughout the entire Roman Empire before a single word of the New Testament was written. We had Catholic saints and martyrs before we had Gospels and Epistles.
The first Gospel was written by Saint Matthew, about 7 years after Our Lord left the earth. The next was the Gospel of Mark, written 10 years after Christ ascended into Heaven. The Gospel of Saint Luke was written 25 years after Our Lord’s Ascension, and the Gospel of John was written 63 years after Our Lord left the earth. The Apocalypse was written a good 65 years after the Ascension of Our Lord. And all of this was written, as Pope Leo XIII reiterates, under Divine inspiration.
If Scriptures are clear to understand, why did Martin Luther and his imitators make new catechisms of Christian doctrine? Why do they fill the libraries with innumerable books of interpretations, explanations and commentaries? Above all, why have they any churches, where the Scriptures are explained, if the Scriptures are sufficient? And if there should be a church, why so many churches, of so many denominations, in every city and in every town? If there is a clear statement that in the Scriptures which all Christians should endeavor to put into execution, it is certainly the desire which Christ expressed in His prayer to the Eternal Father on the eve of His Passion and Death, “That they all may be one, as thou, Father, in me, and I in thee; that they also may be one in us; that the world may believe that thou hast sent me” (John 17, 21). What else do such words mean than that all Christ's followers should first of all have the same faith?—“One Lord, one faith, one baptism.” (Eph. 4, 5).
