Here is a quote from Calvinist Al Mohler provided by Calvinist Justin Taylor on "The Satanic Power of Porn"(http://thegospelcoalition.org/blogs/justintaylor/2012/01/23/the-satanic-...).

Russell Moore (http://www.russellmoore.com/2012/01/23/should-i-marry-a-man-with-pornogr...):

Pornography is a universal temptation precisely because it does exactly what the satanic powers wish to do. It lashes out at the Trinitarian nature of reality, a loving communion of persons, replacing it with a masturbatory Unitarianism.

And pornography strikes out against the picture of Christ and his church by disrupting the one-flesh union, leaving couples like our prehistoric ancestors, hiding from one another and from God in the darkness of shame.

And pornography rages, as Satan always does, against Incarnation (1 Jn. 4:2-3), replacing flesh-to-flesh intimacy with the illusion of fleshless intimacy.

Randolph Sinks Foster, in his book, Objections to Calvinism (1852) writes:

[The Confession of Faith states,] "God, from all eternity, did, by the most wise and holy counsel of his own will, freely and unchangeably ordain whatsoever comes to pass; [and now your disclaimer,] yet so as thereby neither is God the author of sin, nor is violence offered to the will of the creature."

But this disclaimer [God is not the author of sin] by no means relieves my embarrassment -- it greatly increases it, by placing you [Calvinist brother] in the attitude, to my mind, of believing a palpable contradiction, namely, that God did cause all things, sin included, yet in such a way that he did not cause sin.”

Here is another post from Calvinist leader Justin Taylor that leaves one baffled at how Calvinists can hold to exhaustive determinism: 'The 200 Million “Missing” Girls':

A new documentary, "It’s a Girl! The Three Deadliest Words in the World," explores the systematic gendercide taking place in India, China, and other areas of South Asia.

Ram Mushru of The Independent, reviewing the film, writes: “The trailer’s most chilling scene is one with an Indian woman who, unable to contain her laughter, confesses to having killed eight infant daughters.”
