the text in the drawing is an interpretation of a piece from the bible. I'll just google translate:
"St. John Chrysostom

Blessed are the peacemakers, for they will be called sons of God

Here Christ not only condemns the mutual disagreement and hatred of people among themselves, but demands even more, namely, that we reconcile the disagreements of others; and again represents also a spiritual reward. Which one? “For they shall be called the sons of God,” since the work of the Only Begotten Son of God was to unite the divided and reconcile the warring.
