The popular euphemism for "can't we all just be friends" is to give folks "a seat at the table." I've used it. It's helpful. It reminds me that people are people and everyone around the table is coming with different presuppositions, stories, layers, and theologies. It evens the playing field.
More and more, though, what is communicated is that everyone gets a seat at the table and the table is a pulpit for everyone to preach their message. It's the church of all peoples and thoughts and ideas—and it's a veritable mess.
Paul warned the Corinthians that hanging with those intentionally sinning was corrupting the purity of the gospel. Here's what's interesting though: he used the words of one of their own to deliver the warning. The Greek poet Menander first used the words, "Bad company corrupts good morals." Paul contextualized the line for gospel purposes.
What often happens with all these seats at the table is we end up attempting to fit the gospel to sinners, instead of fitting sinners to the gospel.
Bad company does corrupt good morals, and one of those morals is that the gospel cannot be so contextualized that everyone at the table agrees.
If that is difficult for us to swallow in an age where everyone wants meritorious rightness, we're in good company, the disciples once grumbled to themselves, "This is a difficult thing, who can believe it?"
And Jesus, sweet Jesus, gives that wide berth and narrow path: It is the Spirit who gives life; the flesh is no help at all. The words that I have spoken to you are spirit and life. This is why I told you that no one can come to me unless it is granted him by the Father.
Sit with sinners, eat with everybody, welcome all to the table—but remember Jesus is the only one who offers words of spirit and life.
