For one to accept the concept of Purgatory, one must accept the concept of Heaven and Hell. For one to accept Heaven and Hell, one must accept the account of the beginning of humanity literally as presented in Genesis. Science clearly shows that Genesis is figurative. If one accepts science in this regard, one must also accept the reality that all of the stories in the New Testament are figurative also, including Jesus. Think about it.

SCIENCE (from the Latin for 'knowledge') informs wisdom, reason and humanism. This is a 4-legged worldview within reality that maximizes well-being for individuals and society.
