Part 1 reveals the spurious nature of the sources used to establish the truth of Christianity and the existence of Jesus, and the equally spurious methods employed by many Biblical scholars. A brief interlude then leaves no doubt that the existence of the Christ of Faith is virtually impossible, and concludes that even the existence of a stripped-down Historical Jesus is uncertain. Bayesian reasoning is shown to justify sceptical views on many topics, including the existence of God.
Part 2 shifts the focus to the God of classical theism and monotheism, examining the evidence and arguments from scientific, historical, and philosophical perspectives. The inadequacy of the case for God is found to easily justify non-belief (atheism). Furthermore, considerations of alternative gods and conceptions of God, lead to game-changing concerns for Christians, Muslims and Jews.
