Nobody pours new wine into old wine-bottles; or, if they do, the bottles burst, the wine runs out, and the bottles are ruined. But people pour new wine into new wine-bottles, and so both are preserved."

So no one puts fresh wine into old wine bottles; or, if he does, the fresh wine will burst the bottles, the wine will run out, and the bottles will be ruined.

Yes, the overscrupulous brother, for whom Christ died, is ruined by your so-called knowledge.
