I have heard Jesse Romero speak publicly and refer to his experience as a spiritual warrior and deliverance ministry worker. He is a devout and righteous Catholic apologist and warrior for God who is trained in spiritual warfare and deliverance. His experience is primarily in the Latino/-a communities in California.
His relatively short book (120 pages) is a recount of his early experiences and what got him into this ministry. It is not meant to be a biography nor a training book for exorcists. He does give a overview of the great calamity among Catholic lay people, priests, and Catholics - a disbelief in the existence of Satan (Lucifer). Further, he touches on the diminishing of the threat of Satan and his minions by lukewarm Catholics. He also calls out the 'religious' (lukewarm/weak believers) for their embracing of false doctrines such as 'pagan' practices of worshipping 'Santa Muerte,' practicign Santeria, going to psychics, wicca, going to botanicas, 'good luck charms, and talking to the dead.
Mr. Romero lays put the person of Lucifer, the fallen angel and the 'Father of Lies.' Lucifer is the enemy of God and the accuser of men. He also writes about how Lucifer takes advantage of lackadaisical believers, ignorance of the Word of God, and fear. He reminds all that Lucifer is NOT the equal of God like too many lukewarm believers falsely state and believe. God is superior and good. It is only (He) who can defeat the devil and we can call upon the angels, Mary, Jesus, and God when the devil threatens us. Mr. Romero does delve deeply in the Marian opposition to and authority over Satan/Lucifer.
The main part of his book is dedicated to story of the demonic encounters and battles that Mr. Romero has experienced. He focuses on demonic attack because of active mortal sin; generational curses inviting the demonic; making 'deals' with the devil, dabbling in the occult (ouija baords, seers, mediums, psychics, et al), and witchcraft. He illustrates his point with several demonic encounters and deliverances from his career.
He dedicates a section to witches and on is an agreement with the devil. In exchange for their soul, the witch gets powers and earthly victories which are short-lived until they die as a damned soul. He goes into great deal about his experiences with witches, including attempts at cursing him, confrontations, and deliverances of several. He approaches witches with care and the guidance of the Holy Spirit for they are dangerous. He also provides prayers of protection against a witch's curses.
The author also focuses on the 'santa muerte' and 'santeria.' 'Santa Muerte' refers to a demonic and pagan cult that worships a skeletal being dressed in women's fine garments. It is a violent cult that adulterates the Catholic faith. It is closely tied to the drug cartels and represents a demonic religion that promises protection and success to the criminals who worship the demon known as 'santa muerte' (holy death). 'Santeria' is actually voodoo under the guise of fake Catholicism down to the statues. It is also a demonic religion with African origins. It has nothing to do with the Catholic faith other than a loose connection. Both of these cults are marketed through 'botonicas' (occult shops) that operate under the guise of being stores for holistic medical herbs, statues, and religious items. The author warns of Catholics frequenting these storefront sellers of 'santeria' and 'santa muerte' items.
The author ends his narrative section with a chapter on advice to stay away from the occult and spend more time in worship of and God and studying the scriptures. Mr. Romero espouses that the only true strength comes from God and having the mind of God. It is crucial that one commits one's body, heart, soul, and mind to God. As a Catholic, he firmly believes that a belief in and completion of all sacraments will 'seal' one form the devil. Renewing one's mind with Holy Spirit will guard the heart.
The end of the book ends his book prayers of protection, guidance, and deliverance. One should commit these prayers to heart if one plans to battle the demonic.
I highly recommend this book of empowerment and insight.
