It means what it states.
Not the former, and I am curious how that interpretation was reached.
It helps to ignore the chapter markers and go back at least as far as 12:19 because in that verse Paul plainly says one of the mistakes the Corinthians are making is thinking the apostles are defending themselves. Even if the Corinthians were questioning Paul's apostleship, that is not what Paul is writing about. That's not Paul's concern when he directs his
(original) readers to examine themselves. If we go back even further, we see that God has intervened in Paul's life for the express purpose of preventing him from exalting himself. Paul, therefore, cannot be read to say Paul is trying to convince them of his apostleship. The implication is that just as Paul was made to examine himself, so too must the Corinthians. The opening verse of chapter 13 reports Paul is coming as a "
witness," not an authority, not a judge. In the context of a legal proceeding, especially that of a former Pharisees legal proceeding in a Jewish religious court, the judge and the witnesses sit (or stand) in two completely different positions. In the context of a
Christian proceeding Paul later described how the Judge, Plaintiff, Defendant, Prosecutor, Accused, and Witness are all the same person = Jesus! (see the last ten verses of
Romans 8). Paul cannot rationally be construed to be contradicting his own words (even if the Romans text was written many years later).
So..... what does self-examination entail? It must mean an examination of the self solely by means of the written word, the incarnate word dwelling within, and the work of the indwelling Spirit who alone are capable of revealing the truth about and individual to the individual..... while also relying on those God provides the individual for that purpose. Relying on the flesh, even the post-salvific flesh, will not work successfully. Relying solely on the Spirit or the written word will not be sufficient. Solely relying on the written word breeds legalism. Relying solely on the Spirit breeds vacillation and inconsistency. Relying solely on others breeds a variety of ills, mostly establishing a lack of maturity and idolatrous dependence. The results of these conditions are described in Galatians 5:7-21. The alternative is a holistic approach of self-examination that is couched in hearing, understanding, and practicing the revelation of God's sanctifying work in ourselves.
The challenges to self-examination in Corinth were that few had hard copies of scripture, few were able to read, and when the looked to one another for God's revelation their fellow congregant was likely to be a mess! Not only were many of them lacking personal faithfulness (even if they did possess faith), others among them lacked an ability to say and do something about it. No one did anything when a congregant had sex with his mother-in-law! The Corinthian congregations were dividing into sects, pridefully comparing themselves by their personal affiliation with others beside Christ! Why would Paul wade into that mess attempting to convince anyone of his bona fides.
1 Corinthians 1:13-15
13 Has Christ been divided? Paul was not crucified for you, was he? Or were you baptized [r]in the name of Paul? 14I am thankful that I baptized none of you except Crispus and Gaius, 15so that no one would say you were baptized 1 Corinthians 1 New American Standard Biblein my name!
Thank God I had nothing to do with that dross!
Get y'all's act together and ask God to help you examine yourselves, individually and collectively because I am on my way to bear witness to that need. We
all must do so. Immediately after asking God to put the wicked to death he wrote,
Psalm 124:23-24
23Search me, God, and know my heart; put me to the test and know my anxious thoughts; 24And see if there is any hurtful way in me, and lead me in the everlasting way.
The results of
that is....
Galatians 5:22-26
22But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23gentleness, self-control; against such things there is no law. 24Now those who [h]belong to Christ Jesus crucified the flesh with its passions and desires. 25If we live by the Spirit, let’s follow the Spirit as well. 26Let’s not become boastful, challenging one another, envying one another.
Paul's letters to Corinth would have read much differently were those qualities in evidence by witnesses.
