Wait until word spreads that baptism was an ancient Egyptian practice involving sensory deprivation, massive chemical manufacturing operations that took place in ancient Egyptian buildings, theta neural oscillation induced altered states of consciousness, and enlightenment.
They were processing basalt into Epsom salts using, most likely, hydrochloric acid and sulfuric acid millennia before Epsom was even the name of the place on the Earth's crust.
The "fiery baptism of the Holy Spirit" is redundant because the "ba" in "baptism" is pointing to the same thing that "the Holy Spirit" is pointing to. Modern academic consensus interpretations of "ba" are esoterically uninformed.
Christians also don't tend to understand Alpha and Omega or Chi and Rho. Christ did. He got it. Rome, in the first few centuries, button mashed to corrupt and distort the Christ movement away from Christ's teachings and cover up or destroy evidence of Christ's travels during the missing chapters.
Christ was awesome but modern exoteric Christianity requires far too much cognitive dissonance. People are too lazy and egotistical to do opposition research on their own religious beliefs. Often times, it's because they're not closeted in their religious beliefs which is a less costly place to be when switching beliefs. The ego doesn't like to be seen to be wrong.
Also, many have decided that there is no proof of anything out there whatsoever, even though within our lifetimes, the collective knowledge of the world has been becoming ever more available with almost no friction whatsoever in terms of access. We're sitting here with the ability to explore every culture, every religious tradition, every esoteric tradition, every occult tradition, every spiritual tradition, etc. yet people use this tool to do all sorts of idiotic things. Because they've decided there is no proof out there, they do not look, which is ironic because that's EXACTLY what Christ was talking about with the whole camel passing through the eye of the needle teaching.
Most Christians wouldn't recognize Christ if Christ was out on the street corner preaching today.
