The first commandment.

The first three Commandments treat our relationship to God. The last seven concern our relationship with each other. The First Commandment calls us to have faith in the true God, to hope in him, and to love him fully with mind, heart, and will. We respond to God, who has created and redeemed us and extends his providential care to us every minute of each day. The First Commandment fosters the virtue of religion that moves us to adore God alone because he alone is holy and worthy of our praise.
