Not for infants; purify passions before this book

But first we ought to know that, just as childhood is not moved toward passionate love, so neither is the little and infant age of the inner human admitted even to grasping these words — namely of those who are nourished with milk in Christ and not yet with solid food. For unless someone has been purified from the affections of the flesh and from the passions of the soul, and unless more perfectly instructed, that person cannot know these words healthfully. Whoever therefore is not such as to come to this book should neither hear nor read it; otherwise it will give occasion for blasphemy to Jews and Gentiles and heretics.
