The Mass is important to Catholics because
- it is a way of making their lives good again after sins;
- it is the way of gaining the power to fulfil God's will in their daily lives;
- it is an obligation to attend Mass on Sunday to fulfil the commandment to keep the Sabbath holy;
- it is a means of uniting them with Christ and other Catholics;
- it is the Catholic way of nourishing Christians through the Body and Blood of Jesus;
- it is a sacrament of love from God to Christians through the sacrifice of Jesus.
