This is in reference to accusations of misconduct against a person. The testimony of one person against another is not sufficient to prove the defendant’s guilt. Two or more witnesses must agree with the accuser in order to show proof of the defendant’s guilt.
Deuteronomy 17:6
Whoever is deserving of death shall be put to death on the testimony of two or three witnesses; he shall not be put to death on the testimony of one witness.
John 8:16-18
And yet if I do judge, My judgment is true; for I am not alone, but I am with the Father who sent Me. 17
It is also written in your law that the testimony of two men is true. 18 I am One who bears witness of Myself, and the Father who sent Me bears witness of Me.”
1 Corinthians 14:36-37
36 Or did the word of God come originally from you (Corinthians)? Or was it you only that it reached? 37 If anyone thinks himself to be a prophet or spiritual, let him acknowledge that
the things which I write to you are the commandments of the Lord.
2 Corinthians 13:1-3
This will be the third time I am coming to you. “
By the mouth of two or three witnesses every word shall be established.” 2 I have told you before, and foretell as if I were present the second time, and now being absent I write to those who have sinned before, and to all the rest, that if I come again I will not spare— 3
since you seek a proof of Christ speaking in me, who is not weak toward you, but mighty in you.
These Corinthians are not convinced that Paul was speaking the truth to them about the gospel in his two previous visits and in his previous epistle(s). They think that perhaps this is his own gospel and not the gospel of Jesus. So, the next time Paul visits them, he is going to bring two or three fellow Church leaders with him in order for them to testify to them that what he speaks is the truth. Paul wants to reassure them once and for all (by the testimony of two or three witnesses) that he speaks the truth to them.
Also, at his next visit, he will not spare the feelings of those who are now sinning again after their baptisms. He already warned them in his previous epistle(s), but they did not all heed his warnings, “that all persons who break God’s commandments after Baptism/justification are no longer righteous and so they will not inherit the kingdom of God” (unless they repent and obey until death).
Matthew 3:8
1 Corinthians 6:9-11
Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, 10 nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. 11 And such were some of you.
But you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God (Baptized).
This is taken from the earlier epistle which we call 1 Corinthians. Some Corinthians that he had preached to on an earlier visit had repented and were baptized. However, in Paul’s epistle which we call 2 Corinthians, he is telling them that he will not spare any backsliders his wrath when he next visits them.
There must have been an even
earlier epistle that was written to the Corinthians other than the one that we know today as 1 Corinthians as is evidenced by the following:
1 Corinthians 5:9-11**
I wrote to you in my epistle** not to keep company with sexually immoral people. 10 Yet I certainly did not mean with the sexually immoral people of this world, or with the covetous, or extortioners, or idolaters, since then you would need to go out of the world. 11
But now I have written to you not to keep company with anyone named a brother, who is sexually immoral, or covetous, or an idolater, or a reviler, or a drunkard, or an extortioner—not even to eat with such a person. 12 For what have I to do with judging those also who are outside?
Do you not judge those who are inside? 13 But those who are outside God judges.
Therefore “put away from yourselves the evil person” (brother).
