Madeleine Delbrêl is not original simply because she worked unprotected as a Christian in a communist environment alongside communists, but because she carried within her an unwavering, fervent Christian faith that was both naive and deeply reflective. She continuously reaffirmed this faith in a breaking away from all traditional forms, and it instilled in her a love for the Catholic Church that was unshakeable by any painful disappointments. From the mystery of the Church, she drew her life and her boundless loving commitment to her non-Christian brothers. This short book about her aims to approach that innermost source which nourished all her work, a source she never concealed. The fact that all her world-changing power stems from a heart that prays incessantly amidst the hustle and bustle, never turning its gaze away from God, defines her deepest relevance.
