Ten Commandments
In some churches the Ten Commandments are read as part of the worship service.  This is usually followed by a prayer asking for forgiveness. Sometimes in place of the longer reading, the summary of the law given by Jesus is used. You shall love the Lord the God with all your heart, and your neighbor as yourself. The first part is thought to summarize the first 5  commandments, and the last part the last 5 commandments.  Thus the duty to both God and other people is stated.
