From one of my favorite Saints.....my confirmation saint.........always food for thought.....
O Lord, let all the parts of my body, my bones, all the marrow within my bones, be beaten and pounded together in a mortar; only restore Thy Church to her comeliness and beauty
Sorry.....I do not have an actual book resource for this........but my favorite Catherine of Siena book was lent to me by my godmother......and I do not know the title. On my shelf is The Dialogue of Saint Catherine of Siena from Tan Books.
If you do not know Saint Catherine's amazing story......please read it! She was instrumental in returning the true pope to the Vatican in the day when there were "three" popes! God loved Saint Catherine!
