ECHO OF THE HEART OF GOD AND STUDIES OF THE SELF-OFFERING OF ST THERESE OF LISIEUX by Giovanni Gennari
Published in 2001; probably does not have the material contained in Teresa di Lisieux. Il fascino della santità, I segreti di una "dottrina" ritrovata.
Apparently a copy of the latter book was given to Pope Francis in 2013, who took it on his trip to Brazil.
GIANNI GENNARI. Teresa maestra di teologia
If he had had read this book, would Louis Bouyer have revised his opinion of St. Thérèse and praised her even more? Apparently he was already aware of the difference between what is found in the edited manuscripts (which were nonetheless modified by Agnes) of the saint and what was marketed in her name but perhaps he hadn't made such an extensive study as Gennari, who tells the story of Fr. Combes and Hans Urs von Balthasar (both of whose work was used by Fr. Bouyer) and of others in recovering the true teaching of the Little Flower.
