I read most of it on Good Friday and the account of the Resurrection on Holy Saturday. It is one of the most spiritually edifying books that I have ever read. I recommend it that everyone reads this book during Lent. It certainly deserves a 10/10. Below are a few comments that I have written on it before:
"The account I just finished reading of the Last Supper was so poignant and incredibly detailed. I did not know that the Supper Room of Jesus at one time housed the Ark of the New Covenant! Plus, the home was set up so that in the most inner part, Jesus and the 12 disciples ate the Last Supper, while being separated from the other areas by a veil. It is symbolic of the Temple veil! And, the Holy Grail was originally owned by Abraham and even used by Melchizedek!"
I strongly am suggesting this book should be read during Lent. If you don't or can't get a physical copy, you can read The Dolorous Passion of Our Lord Jesus Christ online.
Like all private revelation since the time of the Bible, these visions and promises do not have to be believed by anyone. The Church, in her authority, declares them worthy of belief, but a Catholic does not have to believe them in order to remain a Catholic.
Pope Benedict XV said: "The approbation of such revelations implies nothing more than, after mature examination, it is permissible to publish them for the unit of the faithful. Though they don't merit the same credence as the truths of religion, one can, however, believe them out of human faith, conforming to the rules of prudence by which they are probable, and supported by sufficient motives that one might believe in them piously."
