I. “Sola Scriptura is Responsible for Doctrinal Differences Among Protestants.”
We hear the term protestant so often that it is easy to think that we belong to an inverted form of the Roman Catholic Church called the Protestant Church. This manner of addressing sola scriptura and the supposed problems it causes is fallacious because it groups all non-catholic professedly Christian religious groups under a broad term that (i.)only addresses the group’s disagreement with Rome and (ii.)cannot, by its own definition, signify any one particular group of individuals. The fact that Roman Catholic apologists argue this way shows that their understanding is flawed from the onset. Protestant does not signify a united front against Roman Catholicism; protestant simply signifies an individual or group that has protested against the abominations of the Roman Catholic organization. Muslims argue the same way, interestingly, when attempting to cast doubt upon the Divine origin of the Word of God.
II. “Protestants don’t hold to Sola Scriptura because they need to make a decision to believe the Scriptures, and doing so requires that they believe in a particular interpretation of the Scriptures. But how will they know whether or not the particular interpretation of the Bible they believe is or is not correct? They need an authoritative interpreter of the Scripture: Either they will be that authority, or the Holy Roman Magisterium will be that interpretative authority. ”
To be blunt about this sort of “argument,” it’s stupid. Firstly, Scripture teaches us that the Holy Spirit is the One who reveals God’s Truth to His elect people, so there is ipso facto no need for a “holy” and “infallible” body of interpreters of the Bible. The Holy Spirit is the only Infallible interpreter of His own Word. Every man, excepting Christ, is a sinner and is, therefore, liable to interpretative error. The argument is already refuted, but let’s look at another aspect of the argument that is equally false (and stupid), viz. the false dilemma that Catholics claim “the protestants” will face. If Sola Scriptura is false because it requires us to make a decision to believe a particular interpretation which we cannot know for sure has or has not met with Christ’s approval, then the Magisterium is also to be rejected, for they stake their claim to authority on the basis of their interpretation of Matthew 16:18-19. How can we know that their particular interpretation has been authorized by Christ if they are appealing to their interpretation of Scripture that they claim has been authorized by Christ?!
This is not only viciously circular, it is also a concealed appeal to authority and is, therefore, doubly fallacious. The Roman Catholic either autonomously accepts the Magisterium’s interpretation of Scripture – without having any way whatsoever to prove whether or not their interpretation of Scripture has been authorized by Christ – and thus overrides the authority of the Magisterium and sins against God (by God’s command no less!), or he tries to suffocate his conscience which is very loudly condemning him for fighting God and His Christ.
