The Combined Church of Earth is the primary religious force in space. At the turn of the 24th Century, when the first fleets were being raised, the various churches feared the loss of influence they were bound to suffer when Earth was now one of three habitable worlds. Humanity was focused on the stars, not the Heavens.
The 4th Fleet was assembled to be the protectors of humanity in places far from Earth.
While the Church’s parent organizations on Earth continue to bicker and fight amongst themselves, the separate faiths that make up the Combined Church co-exist peacefully. The men and women of the Church have put aside their zeal for argument, instead turning their energies toward helping the weak and downtrodden of the Empire of Terra.
