OK, so maybe psilocybin can "occasion mystical-type experiences having substantial and sustained personal meaning and spiritual significance," but is that the same as seeing God? No, the CBC reports, in a story headlined "Mystical Magic Mushroom Experience Not God in a Pill." Quoting a theologian (presumably because God did not respond to requests for an interview), the CBC explains that "magic mushrooms taken by hippies do produce mystical experiences, but they should not be confused with faith." University of Toronto theologian Dave Reed has this to say regarding the Johns Hopkins study that prompted the news media's sudden interest in psychoactive fungi: "All this did was stimulate that part of the human personality that produced certain feeling states and altered states of consciousness. Those are no criteria for an authentic encounter with God."
The CBC failed to ask the obvious follow-up question: What are the criteria for an authentic encounter with God? According to Deuteronomy (13:1-4 and 18:22), they are as follows:
1) Any predictions based on the encounter have to come true.
2) Any messages derived from the encounter must be compatible with God's earlier commandments.
In addition to casting doubt on the authenticity of mushroom-eating hippies' encounters with God, these criteria seem to render Christianity (and Islam) invalid.
