Martin Luther began the Protestant Reformation (sixteenth century AD) with the concept of sola scriptura (scripture alone) as the final authority in doctrinal matters.
The Council of Trent convened that same century and solemnly defined that the Church, or more precisely, the teaching authority (Magisterium) of the Catholic Church had the ultimate and last word—not because it is superior to the Bible, but because the whole of divine revelation, from Sacred Scripture (Bible) to Sacred Tradition, was entrusted to the Church for protection and for proper interpretation.
Nowhere in the Bible does Jesus say to read, but He does often command that we listen. The written word did not come immediately, but the spoken and unwritten word did follow after Jesus performed His many miracles.
Matthew 16:18–19 is the famous passage where Jesus says to Simon, “And I tell you, you are Peter, and on this rock I will build my church, and the powers of death shall not prevail against it. I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.”
The Greek word ekklesia is translated as “church.” The passage makes it clear that the Church is built by Christ, it is His Church, and it has the power to bind and to “loose” in heaven and on earth. How can the Word of God go against the will of God?
If it is Jesus who built the Church and He gave it full authority to teach in His name, then there is no competition between the Bible and the Church any more than there can be opposition between Sacred Scripture and Sacred Tradition.
