1 Corinthians 10:15
I am speaking to you as [I would] to sensible people, [so] judge for yourselves what I am saying.
1 Corinthians 8:1
I now want to reply to the matter of idolatrous sacrifices [which you wrote to me about]. We know that we all possess knowledge. [Note: This may be a statement posed to Paul by the Corinthians, who seemed quite preoccupied with "knowledge"]. Knowledge [only] makes people arrogant, while love builds them up [spiritually].
1 Thessalonians 5:21
Put everything [i.e., speakers and their messages] to the test, [then] hold onto what is good.
1 Corinthians 4:10
We are "fools" for Christ's sake, but you people [think you] are "wise" in [the fellowship of] Christ. We are weak, but you people [think you] are "strong." You are honored, but we are despised.
1 Corinthians 6:5
I am saying this to make you ashamed. Can there not be found one wise person [there] among you who is able to decide [on a matter] between his [Christian] brothers?
1 Corinthians 11:13
[So], judge for yourselves: Is it proper for a woman to pray to God [in the assembly] with her [physical] head uncovered [i.e., by hair or a shawl]?
1 Corinthians 14:20
Brothers, do not be children in the way you think, but be babies in wrongdoing; yet be mature in your thinking.
