Blasphemy of the Holy Spirit - RC Sproul
What is blasphemy of the Holy Spirit? According to RC Sproul, its recognizing that Jesus is God and accusing Him of being a devil. Theodicy is an explanation for the existence of evil, specifically a defense of God in light of evil's existence. RC Sproul affirmed the Westminster Confession of Faith and was an Augustinian. As such, he concluded God ordained whatsoever comes to pass. Ordain means to confer holy orders, command and decree... thus to ordain evil is to be the cause of evil.
This polemical work is intended to show how if one is consistent with their application of determinism, as articulated by Augustine, the Westminster Confession and Sproul... one must conclude God is responsible for all evil in the world. You will note how RC Sproul insinuates here that God created Adam and Eve intending them to sin, thus condemning himself per his own standard.
