Can it be proven that Christ is risen?
If Harry did not believe the Philadelphia Phillies won the 1980 world series, he would likely change his mind if it could be proven from Baseball Almanac. Similarly, if Harry did not believe Calvin Coolidge was the 30th President of the United States, The Complete Book of U.S. Presidents would more than likely put the matter to rest for Harry. Similar examples could be given for state capitals, the location of famous rivers and so on. The point should be apparent. What one will accept as proof will depend upon what one accepts as authoritative.
The reason people are willing to change their minds on such matters after being confronted with a reliable, even an authoritative source, is because not much is at stake. It does not dramatically affect one’s worldview whether Calvin Coolidge rather than, say, Herbert Hoover was the 30th U.S. President. Just like it does not disrupt one’s worldview if one mistakes the winner of the 1980 World Series with the winner of the 1981 world series. Adjusting relatively inconsequential beliefs is not a matter of grave concern. Nothing major is at stake, other than perhaps a little pride.
In both cases, we may say that what was first in question by Harry was later proved true by a source worthy of acceptance. We may also say Harry became persuaded. Moving forward, we would do well to maintain a clear distinction between the objective nature of proof and the subjective nature of persuasion. The question before us is whether proof is ever dependent upon the result of persuasion.
Now what if Harry did not readily accept the testimony of a book on U.S. Presidents right off the bat? In other words, what if Harry was not immediately persuaded by an appeal to an authoritative book but then after further reflection realized the book must be correct. Obviously Harry’s disbelief would have given way to belief. Harry would have become persuaded by the proof for Calvin Coolidge as America’s 30th President. It is also noteworthy that the proof Harry would eventually be persuaded by never changed. Therefore, the proof itself did not become more persuasive. Rather, a valid proof with a reasonable premise (that such books are typically reliable) eventually persuaded. The variable was Harry. He changed. The proof remained constant. It did not change.
Lest we confound the objectivity of truth and what constitutes sound argumentation, we must maintain that Calvin Coolidge was objectively proven to be the 30th President of the United States prior to Harry becoming subjectively persuaded by the proof. If not, then objective proof would be dependent upon subjective results, in which case arguments could become sound (or go from weak to strong in the case of inductive arguments) after they are subjectively accepted, which would collapse proof into persuasion. It could not be proven to a philosophical skeptic that there is a tree outside the window or the cat is on the roof.
Putting this all together, if persuasion is a matter of what one will accept as authoritative and a sound proof is a matter of validly presented truth, then the resurrection of Jesus Christ can be proven from the Bible regardless whether the unbeliever rejects the authority of God’s word. If proving secular historical facts from fallible and potentially errant books is not dependent upon consensus, then how much more the case with facts contained in God’s infallible and inerrant Word? The issue at stake is what one will accept as authoritative.
Now obviously I would not expect an unbeliever to submit to the objective authority of God speaking in his Word without the Holy Spirit’s sovereign work of subjective persuasion, but neither should I expect a Christian to deny that the Christian worldview can be proven true from the Bible. Comparatively speaking (and whether one accepts it or not), we have it on greater authority that Christ is risen than Calvin Coolidge was the 30th U.S President (or the Phillies won the Series in 1980). Uninspired history books can err. God’s Word cannot.
At the heart of apologetic methodology is ultimate authority. How the authority of Scripture should shape the Christian’s defense of the faith is a matter of bringing every thought captive to the obedience of Christ, (even as the Christian gives an answer for the hope that is in him, with meekness and fear.) How consistently the believer sanctifies the Lord God in his heart will determine his general apologetic methodology.
