Under the Protestant/Sola Scriptura (the Bible alone) theological system, is it your belief, and would you agree, there exists no person or no institution that can infallibly decide what is true and what is false for Christians when it comes to matters of faith and/or morals?
Correct
Faith comes from hearing the Word of Christ
But we must remember that God has gifted humans with the capacity to know the truth and act on it. In fact if this were not so He could not judge our response to His Word.
If you happen to answer yes to this question, my next question would be.... under this theological system, would you agree there is no sure way you could have absolute assurance of anything you believe being true? In other words, there is no way of knowing the truth?
Not correct -
Consider this from Romans 1...
18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness;
19 Because that which may be known of God is manifest in them; for God hath shewed it unto them.
20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
21 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.
22 Professing themselves to be wise, they became fools,
23 And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
24 Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:
25 Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
26 For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature:
27 And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.
28 And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;
29 Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,
30 Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,
31 Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:
32 Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.
So God has evidenced Himself to all individuals direct to the human spirit.
Yet, Jesus says, "Know the truth and the truth will set make you free." (
John 8:32)
So, let me leave you with this last question: For a Christian, what is the pillar and ground of the truth - i.e., the upholder and foundation of the truth? Is it the Bible? Yes or no?
It is the Word of God that He makes manifest in us.
Scripture alone without Him can never be inerrant.
