Religion is deemed to follow similar patterns to that of a virus, in that it requires a host to reproduce and spread its self to others and it cannot survive with out one. There are many different strands all competing for hosts.
Although the particular strand depicted here destroys its host’s cells during its reproductive cycle, not all strands are considered pathogenic to a person’s health; many exist in a symbiotic relationship.
The virus is considered to be loosely hereditary, but many offspring escape infection and build up a natural immunity via a mechanism which is yet unknown. This immunity can be broken down quite suddenly during times of great stress or trauma.
In many cases those infected to a high degree congregate in large groups on specific time cycles and often send individuals to infect others, with varying rates of success.
