According to St Maximos the Confessor there are three motives for writing which are above reproach and censure: to assist one’s memory, to help others, or an an act of obedience. It is for the last reason that most spiritual writings have been composed, at the humble request of those who have need of them. If you write about spiritual matters simply for pleasure, fame or self-display, you will get your desserts, as Scripture says (cf. Matthew 6:5,16), and will not profit from it in this life or gain any reward in the life to come. On the contrary, you will be condemned for courting popularity and for fraudulently trafficking in God’s wisdom.
~St Gregory of Sinai
