Mention “miasma,” “pollution,” or “purity” in regards to Polytheism, and many Pagans will take umbrage with these terms. One reason is that Christianity has redefined these Polytheistic terms to match its theology. Since many Pagans are converts from Christianity, they will often think of these concepts in those terms. However, “miasma,” “pollution,” and “purity” had different meanings in Polytheism.
Paganism does have its version of “pollution” and “purity.” Pagans discuss “positive” and “negative” energies. People will cleanse themselves and their spaces routinely to clear out negative energy. For example, crystals are often cleansed before using them. Also, before rituals, many Pagans will smudge themselves to purify themselves and to clean out the ritual space.
Miasma and spiritual pollution are different from both negative energy and Christian sin. Negative energy powers destruction, sickness, and other such things. It can be removed by laughter or positive thinking. Sin is removed by baptism and confession. Miasma, which is specific to Greek Polytheism, is a “spiritual pollution that prevails over all, it is not an ‘evil thing.’” Continuing in his essay, Markos Gage says “Miasma is therefore something we incur in life, everyday life.” (Note 1)
In Roman Polytheism, castus (the adjective) means being morally pure, pious, or ritually pure. Piety (pietas) is maintaining the right relations between people, their Gods, their families, and their communities. Castitas (the noun) is the purity of the ritual and the participants. (Note 2) That means everyone must be physically and mentally cleansed before conducting a ritual. Before a ritual, people perform ablutions by washing their hands and asking that the water purify them.
An error conducted in a ritual is a spiritual pollutant. It negates the ritual and risks the anger of the Gods. It is not that a God will smite someone, but is to maintain the Pax Deorum, the Peace of the Gods. Religious negligence leads to divine disharmony and the turning away of the Gods. This leads to the loss of protection for the family, community, and the individual.
The closest thing that Roman Polytheism has to Christian sin is nefas. This can be defined as anything which is contrary to divine law. Nefas is a failure to fulfill a religious duty. Nefas is a willful act of religious violation.
Polytheists regard the world to be neutral, which differs from Christian theology. St. Augustine stated that the world is both corrupt and corrupting. Therefore, humanity lives in a Fallen World. To Polytheists, the world is both clean and dirty. Kenaz Filan explains, “The world is a clean flowing stream, and miasma the sewage dumped into the water. We clean the stream by filtering that sewage or by redirecting it…to where it can be properly contained.” (Note 3)
Why focus on purity and pollution? When a person prays, divine, or perform any other sacred act, they are engaging with the Holy Powers. There is a doctrine in U.S. law called, “Clean Hands” (also called “Dirty Hands”). (Note 4) The plaintiff cannot have the judge participate in an illegal act. One example is a drug dealer cannot sue to have his stolen drugs be returned. Another is suing the hit man you hired to kill someone for failure to do their job. As Judge Judy says on her TV show, “the courts will not help anyone with dirty hands.” I believe that in our relations with the Gods, we can think of purity and pollution in those terms.
