Taking The Lord’s Name In Vain
The third of the Ten Commandments is Thou shalt not take the name of the Lord Thy God in vain. The standard interpretation for this commandment is that we should not swear or curse using the Lord's name. But I can think of another interpretation that has to do with the Sacrament. When we partake of the Sacrament we promise to take upon us the name of Jesus Christ. So, in the context of the Sacrament, taking the Lord's name in vain would be like taking the Sacrament without a sincere effort to keep the commandments and always remember Jesus Christ and strive to have His spirit be with us always. Just like we should never curse or swear using the Lord's name, we should never partake of the Sacrament unworthily or dishonestly, as both are examples of taking the Lord's name in vain.
