2 Corinthians13:2

The phrase “those who sinned” tells us there were still improper things going on in the church of Corinth, some of which were out-right sin. That phrase is probably referring to people other than the immoral man because he had already been disciplined and had repented. There were others who were guilty of various things that had negatively impacted the congregation who had not yet been confronted about them.

The phrase, “and all the rest” tells us that Paul was holding partially responsible the people who sat by and watched without doing anything while others committed terrible acts. The leadership had not led properly in those days, and Paul intended to hold him or them accountable.

Now let’s look at the clause “if I come to the [same]”. Some translations ignore the word “if” in this verse, but it should not be ignored. The Greek text actually says “if I come to the again”. It seems obvious that something is missing between “the” and “again”; the article is dangling in midair with nothing attached to it. It makes the most sense to add words such as “same situation”, making the clause read, “if I come to the same situation again”. I think Paul wrote it the way he did because there was no need for him to define it or mention details; they knew what he was talking about. This means that if Paul found any of the same situations addressed in the earlier letter we call I Corinthians, some of which he mentioned briefly in II Cor. 12:20 as still being concerns to him, he would deal with them forcefully; he would not go easy on the guilty because that had been done too many times already by the leader of the congregation with nothing good to show for it.
