I. “You Shall Worship the Lord Your God and Him Only Shall You Serve”

From The Catechism of the Catholic Church

2091
The first commandment is also concerned with sins against hope, namely, despair
and presumption:
By despair, man ceases to hope for his personal salvation from God, for help in
attaining it or for the forgiveness of his sins. Despair is contrary to God’s
goodness, to his justice – for the Lord is faithful to his promises – and to
his mercy.
