The Satanic Temple website states they do not believe in a personality called "Satan". It is here that the philologist says "fraud". This organisation has created a new definition of Satan, no doubt, because a "humanist" organisation would not receive the tax exempt status that is accorded a religious entity.
On this website, I have documented their attempt at placing a Baphomet statue in Oklahoma and holding a Satanic Mass in a civic center. Although the attendees at the mass must be at least 16, one wonders what delights the after-party may include.
I take notice of these headlines neither because I am Pro Satan [whether in the traditional understanding of Satan or the Modern meaning] nor because I am anti-satanic, but I relate these incidents because I find these revelations interesting, without moral judgement, whereas philosophically they have have been judged and found wanting.
The modern Satanic Mass, as well as their 19th century French counterparts, are nothing more, and nothing less, than an attempt to shock and outrage sensitive people. We understand that to invoke Satan, rather than the legions of inferior demons, is impossible. Needless to say, the Master has never appeared nor will ever appear to those who are enfeebled by sensuality. Therefore, theses rituals have only one purpose: shock and awe.
When the colonies rebelled against the crown in 1776, the creation of the first non Christian country in Western history would be the result. The American Union was the first Western country without a Christian monarch and, therefore, secular from creation. Sham arguments regarding the founding fathers Christian beliefs are dismissed when one reads the Declaration of Independence and the Constitution, that is to say, no references to Jesus are found, but only references to God. This God is not of the Jehovah of the Bible. "Deism is the belief that reason and observation of the natural world are sufficient to determine the existence of a Creator, accompanied with the rejection of authority as a source of religious knowledge." [per Wikipedia]
As of this writing, the following countries have a Christian monarch: United Kingdom, Norway, Sweden, Denmark, the Netherlands, Belgium and Spain. Only Spain is a predominately Roman Catholic country. Because of the United State's radical break with western tradition, it would be only a matter of time until long established churches came under attack from Satanic Cults. We use the phrasing "established churches" because only in the Modern age would people call themselves Christians, when in fact, they are not Christians.
In the Modern Age, people state that they are Christians because of their belief, or their behavior or a single action (Baptism, for example). Historically speaking, these people are in grave error and create scandal. They falsely claim to be Christians, even though most have not been anointed with oil (chrism) and, hence, not Christian.
We can confidently state that many professing Christians have been misled either by other's deceitful practices or their own complacency. Regardless of these professing Christian's erroneous beliefs, the Satanic Temple and similar organization will exist for some time, due in no small part, to our secular Constitutions and laws. Perhaps these organizations and establishments will survive until the end of Modernity.
Gentle Reader, as always my opinions are irrelevant, while my informed opinions may or may not be interesting. However, for the rational mind, observations, facts and reasoning will always take precedence over opinions.
