As the interior movement increased, she was impelled to confer with intelligent friends in the distance concerning this most momentous interest of her life. Especially with Overbeck there ensued a correspondence which, continuing for years, was of great assistance in attaining to religious clearness. Overbeck took kindest interest in her doubts and scruples. He had formerly gone over the same ground, and could therefore confer with her about such matters "as a brother." His letters grew into a connected vindication of Catholic doctrine, and the truth and beauty of the church, expressed in the mild, clear, fervent, and touching language of one equally worthy of respect as man and artist. With a nature like Overbeck's, where the man and the artist are not two distinct individualities, but are united in a higher form --Christianity--words have a more elevated significance; and a correspondence with him must have necessarily possessed an import more than usually edifying. Emily Linder deeply felt this. We take her own testimony when we say that Overbeck's letters contributed largely toward her religious development; and, by the overwhelming conviction of his words, no less than by his own deep spirituality, she attained to a knowledge of very vital truths. She viewed the assistance he rendered her in the light of a perpetual obligation; and in later years, long after she became a Catholic, she breathed, in her letters to the admirable master, a "God reward you for it." Meantime, however, she had to pass through many a severe struggle. The wrestling and testing which her conscientiousness imposed upon her was of long continuance. The dread of a hasty step which might afterward plunge her into the deepest unrest, caused her to advance but cautiously. Her mental vacillation continued for quite a period, during which she was filled with unsatisfied spiritual yearnings. She stood just on the portal of the church, afraid to enter. Many a prayer, far and near, ascended in her behalf to heaven. Brentano lived not to witness the conversion he so longed for. But the hope which gladdened his last days attained a realization the year after his death.
