Forcing a Church Reverend to translate the book yielded a ton of chaotic information, which took a real effort to piece together into a comprehensible form, which is as follows.
The first part of the book concerns Church cosmology. It claims that the Stellar Empire dates back millions of years ago. They were busy seeding life on various planets, until a mysterious enemy, known only by the name of 'Inciters' appeared. A schism took place - the Star Gods as we know them today abandoned the old ways to better fight the war; other Star Gods, henceforth called the Elder Gods, claimed that convenience doesn't justify abandoning the old ways. The Church, therefore, is obedient to the Empire, but it also secretly holds the Star Gods to be imperfect.
The second part of the book concerns Church philosophy, described by words Pleasure in Perfection, Elegance in Timing, Refuge in Creation. Reading between the verses, you can feel their loathing towards the Academy in particular, but also, strangely, towards the Reticulans. In contrast, the Deep Ones are seen as pure.
The third, most exciting part, concerns performing VooDoo rites - we're ready to start experiments at any time!
