I recently finished “The Father of the Little Flower” by Céline Martin.
There are many wonderful details in his life given there that are not in St. Thérèse’s autobiography.
One can understand why St. Thérèse was able to see how merciful, just and loving God the Father is. She had a perfect example in front of her eyes, he was truly another St. Joseph. A beautiful man. His example gave the foundation for her Little Way.
