As far as Roscirucianism goes, it's a sham. It presents itself as almost a Catholic Freemasonry group, however, they are fairly close to demonic magic. There is a difference between spiritual warfare and the Satanic occult. In the Bible, with the fall of man and Cain's murder of his brother, there was a split in spiritual power between those who would become the Masons and utilize the knowledge of God against the light. The Rosicrucians and Masons trace their own lineage back to the line of Cain, and hold Nimrod (Dictator after the flood against God, ordered the tower of Babel to be built, etc.)
My grandfather (A Puerto Rican Rosicrucian) was a very messed up man. His practices, which I've come to know more about since his death, were honestly disgusting. He moved out of he and my grandmother's room and into his own, he always kept his door locked and would be lost in ritualistic prayer most of the time, only coming out at night. He became more abusive towards my mother and aunt, he gave himself over to dark things that affected my family and me directly even now. It's been about 17 years since his death, and the more I've delved into the Rosicrucians Masons, the more disturbing things I've found.
When it comes to Christianity and spiritual warfare, THEY are the kinds of people we fight against.
