Some of you may know what it is, others; an idea of what it is and most of you: no idea whatsoever...
If anyone has had the opportunity and misfortune of studying the liturgy (Latin or translated versions) of the Black Mass as extensively as I have, you will, no doubt, also have knowledge of the strands of Non-/ Theistic Satanism, but for those that don't: allow me to explain briefly (very briefly, this stuff is extensive!) some back-story to the whole situation, what happens, the issues which arise from such events and the theology behind it all...
The Satanic Black Mass, usually performed by theistic Satanists (Meaning that the Devil or Satan, etc. is a dualistic, REAL power parallel to the Trinitarian God: Father, Son and Holy Spirit) to invoke him for fulfilment of intentions, just as the Catholic Mass is offered for various intentions to God. The Liturgy of this Black Mass is usually a polarised formula of what is known as the Extraordinary Form of the Mass or a Pre-Second Vatican Council version of the Mass. It is in Latin, and has references to Heaven, God, Jesus Christ and the Holy Spirit removed and replaced with descriptions glorifying Hell and such like. Additionally, the Host (which is the wafer used in the Catholic Mass to be consecrated by a priest or bishop to be made the body of Christ) is somehow taken from a Catholic church, having been consecrated and made the Body of Christ and is abused in the Black Mass.
This is the most profane part of the event, a mass which has been constructed in sole purpose and intention to mock and ridicule a Faith and it's beliefs, manages to take what is believed by 1.2 Billion Catholics, and more if you are to include other Christians whom believe in the transubstantiation, (the aforementioned Body of Christ in the Host) in the world to be Christ in a Sacrament, a sign of his presence on Earth, and remove all dignity by irreverence through abuse to the Host. The abuses I write about are through releasing certain bodily materials and other unmentionable things onto it. A further act is that in some Black Masses, there have been instances in which people have been kidnapped and forced to be used in a mass for the most heinous and unthinkable of things, as was the case in Italy a few years ago. It seems that cults over the last decade all over the world have been increasing, and as such, even if people join for fun or curiosity, the opportunity for these masses may also increase, and hopefully not increase other people being dragged into it.
I fail to see how a civic centre and government institution can allow a surely fear-mongering mockery to take place, especially in a country which has been so heavily influenced and accumulated great progression through Christian involvement in politics. Sacrilege, even if only demonstrated as 'educational' is not free speech, is not an expression of free speech when it offends and takes what a vast percentage of the world population holds close to their heart to deface it.
This event has already grabbed the attention of the Archbishop and Bishop of Oklahoma and Tulsa. They are urging people (and I ask too, for any of you too who can see the issue as a matter of principle) to pray, particularly the prayers of St. Michael and Pope Leo XIII.
The people's voice mattered and was heard when this had taken place in Harvard, and so the chance to voice against it again can happen, there is a petition on-line, which you may find here: http://www.tfpstudentaction.org/stop-black-mass-oklahoma-city.html#.U-DRhQQ_BRE.facebook
