The approach to authority is very different in the ancient Church than in the modernist Protestant church. The Catholic Church follows the “Word of God alone” while the Protestant ecclesiastical groups follow Sola Scriptura which states that only God’s written word is authoritative. The latter is a sixteenth century man made doctrine designed to destroy the unity of the Church and fragments the entire body of Christ by exponentially increasing schisms caused by accepting only part of God’s word by the Protestants. Sola Scriptura is not a doctrine for a better understanding of the Logos but instead is designed to circumvent the legitimate authority of the Church given by Christ.
It is the belief of the ancient Church that is the Magisterium of the Church that has the authority given by Christ to expound on, recognize and guard the Word of God. The Word of God is not only the written Scriptures but all that is handed to the Church by the Holy Spirit. In so doing and carrying out her responsibility the Church is the true servant of the Word.
God’s people have never been Sola Scriptura advocates. In Jesus’ day the orthodox Jews were not, nor were Jesus or the apostles. The continuation Sola Verbum Dei is a theological continuation of God’s Word from the Old Covenant to the New. The only ones who believed in anything resembling Sola Scriptura were the Sadducees who were the theological liberals of their day. We know that the first century Christians did not believe in Sola Scriptura by the teaching of St. Paul in Holy writ:
(2Th 2:15 DRB) (2:14) Therefore, brethren, stand fast: and hold the traditions, which you have learned, whether by word or by our epistle.
The Church teaches that the Word of God is the Logos:
(Joh 1:1 DRB) In the beginning was the Word: and the Word was with God: and the Word was God.
(Joh 1:2 DRB) The same was in the beginning with God.
(Joh 1:3 DRB) All things were made by him: and without him was made nothing that was made.
(Joh 1:4 DRB) In him was life: and the life was the light of men.
So the question among Christians should not be what is the Word but instead how is the Word revealed to man. To the Protestant the Word is only revealed in written form called Sola Scriptura. To the Catholic Christian the word has a much broader meaning and is revealed to man in more than a written form where men were inspired to reveal God’s Word. Catholics believe that inspiration is not only personal as with the biblical writers but is also revealed to and through the Church such as in the Ecumenical Councils and through the authority exercised through the Church to recognize, guard, interpret and teach the Word. The Church throughout history has faithfully exercised her authority to guard the word of God against the attacks of heresies, such as Sola Scriptura.
