The Fellowship runs its own printing press, established by Max Heindel in 1912, which is an area of great activity with hundreds of products being produced: printing the ephemerides, "the books" (with millions spread worldwide), most of "the course materials" sent to the members, the periodical "Echoes from Mount Ecclesia" (which became the "Rays from The Rosy Cross" in July 1915), the pamphlets (in six languages) that are distributed freely to people and many other various things, such as flyers, brochures, postcards, posters, etc., that are necessary for the diffusion of "the Rosicrucian Christian teachings", the Gospel of the coming Age of Aquarius. The organization generated so much mail that the federal government built the city's first post office on Seagaze Drive in 1936 to keep up with the demand.
