Those who still fear the war against the passions and dread the assaults of invisible enemies must keep silent; in their struggle for virtue they must not enter into disputes with their enemies but through prayer must entrust all anxiety about themselves to God. To them apply the words of
Exodus: 'The Lord will fight for you, and you must be silent' (Ex. 14:14).
