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

2094
One can sin against God’s love in various ways:
– indifference neglects or refuses to reflect on divine charity; it fails to
consider its prevenient goodness and denies its power.
– ingratitude fails or refuses to acknowledge divine charity and to return him
love for love.
– lukewarmness is hesitation or negligence in responding to divine love; it can
imply refusal to give oneself over to the prompting of charity.
– acedia or spiritual sloth goes so far as to refuse the joy that comes from
God and to be repelled by divine goodness.
– hatred of God comes from pride. It is contrary to love of God, whose goodness
it denies, and whom it presumes to curse as the one who forbids sins and
inflicts punishments.
