This book was recommended by a sincere Catholic. It was begun in 1637. Then, after eight years of work, the authoress burned it. Obediently, she wrote all four volumes again. She began the re-write in 1655 and finished it in 1665. The original manuscript is still in the Convent of Agreda, where she served, against her wishes, as abbess.
She makes a point near the beginning of Volume 1, that Mary had to have been programmed at the same time The Father and The Son, with the Holy Spirit, began The Creation Program. She states what is obvious, once we absorb it, that a perfect vessel for a Perfect Being must have been provided.
When John Adams served the United States in France, during the American Revolution, he had a conversation with a French prelate, in which he was told something like: “You (Protestants) believe in The Trinity. It is we Catholics who determined that there were Three Divine Persons in The Trinity. We could have said that there were, four if we had thought it proper to include The Blessed Mother.”
So, The Church, guided by The Holy Spirit, determined that God was in Three Persons. Mary, alone among humans, is the only One so important that endless debates took place about the nature of Her being.
