The Union of the two Mary's
Picture this. Fr. Lataste explains his idea to Mother Henri-Dominique. She gasps. Her eyes widen. With a long intake of breath, she asks, "Moi?"
She is being asked to begin a congregation, not just be a humble member of an existing one. She had thought she was entering an established community. But... but...but it didn't even exist! It was just an idea of Father Lataste's.

...at the same time light shone in my--up to that point--troubled and hesitant soul; in an instant all my objections faded away. But at the same time, I experienced in my very depths the feeling of an abandonment which was to weigh on me, as upon the dying Savior, in order to succeed in bringing about the union of fallen souls and faithful souls. I experienced the anguish of heart of a mother who senses the unhappiness of an abandonment to which she and her children would be vowed.
