Paul appears to be saying to the Corinthians in 1 Corinthians 3:21–23 that as long as they refrain from interfering with the foundation, which is Christ, they should have no concern about who is teaching them. Does he support all speakers in the future or just the apostles? In other words, does the apostle Paul's "all things are yours" speech only assert that all of the apostles are equal, or does it also encourage his listeners to be more "liberal" about their sources?
