“You shall love the Lord your God with all your heart, and with all your soul and with all your strength.”1
The first commandment summons man to believe in God, to hope in him, and to love him above all else.
“You shall worship the Lord your God.”2 Adoring God, praying to him, offering him the worship that belongs to him, fulfilling the promises and vows made to him are acts of the virtue of religion which fall under obedience to the first commandment.
The duty to offer God authentic worship concerns man both as an individual and as a social being.
Superstition is a departure from the worship that we give to the true God. It is manifested in idolatry, as well as in various forms of divination and magic.
Tempting God in words or deeds, sacrilege, and simony are sins of irreligion forbidden by the first commandment.
