Would any of the wonderful Catholic posters here be willing to tell me of one book (besides the obvious Bible, Catholic Catechism, etc.) that has helped them the most on their spiritual journey? How 'bout three books:
The Soul of the Apostolate by Jean-Baptiste Chautard
I Believe in Love by Jean du Coeur de Jesus D'Elbee
Abandonment to Divine Providence by Jean-Pierre de Causade
