This chapter has two main topics: head covering and communion
Follow my example, as I follow the example of Christ.
1 Corinthians 11:1
Every man who prays or prophesies with his head covered dishonors his head. But every woman who prays or prophesies with her head uncovered dishonors her head—it is the same as having her head shaved.
1 Corinthians 11:4-5
So then, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord. Everyone ought to examine themselves before they eat of the bread and drink from the cup. For those who eat and drink without discerning the body of Christ eat and drink judgment on themselves.
1 Corinthians 11:27-29 NIV
