☢The Theistic Response➼ to Atheists saying, "It Doesn't mean God Did it"

[Astreja]

LaVey states that “Satanism encourages any form of sexual expression you may desire, so long as it hurts no one else.”

Sounds fine to Me.

First Corinthians 6:18-20 commands us to “flee from sexual immorality..."

I really don't think that the wittering of Paul the Antichrist is a particularly good guide to sexual best practices.  That said, "any form of sexual expression you may desire, so long as it hurts no one else" doesn't happen to qualify as immorality in My book anyway.

"...Do you not know that your body is a temple of the Holy Spirit..."

No evidence for such an entity as the "Holy Spirit."

The Satanic bible concerning the existence of the afterlife is that there is no such thing as life after death, and thus life must be lived to the full in this world. This is the premise on which many of the Satanic teachings are based, for it removes the element of accountability...

Not so.  We are indeed accountable to one another in the real world, rather than to some hypothetical supernatural being.

Eternal destruction is the only thing that will result from {Satanism's} false teachings. The fires of hell will be a bitter reality for those who have been taught that hell does not exist.

I am so sure that hell is mythical (probability of .999...) that I am prepared to take that chance.  In the infinitesimally small probability that hell does exist, I choose to go there anyway rather than spend eternity in the presence  of a god that deliberately created hell.
