What is Lucifer? He is a brilliant intelligence, the most enlightened of all, but an intelligence discontented with God and his order. The mystery of iniquity is nothing but the result of this discontent manifested in as many ways as possible.
Lucifer, as far as lies in his power, wishes to leave nothing in the state in which God has ordained and placed it. Wherever he penetrates, you will always find the work of God disfigured. The more lights, knowledge and general capacity a person has the more he is to be feared, if he has not the foundation of piety which consists in contentment with God and his will.
— Father Jean-Pierre de Caussade, S.J.
