Is there a wrong way to take communion?

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

            Paul said that worst thing you can do before communion is not to examine yourself and confess.  You must understand the ways you have sinned against Jesus and discounted all the things that he died to save you from. 

            Take a moment before communion to confess your sins.
