People with a higher caffeine intake, from sources such as coffee, tea and caffeinated energy drinks, are more likely to report hallucinatory experiences such as hearing voices and seeing things that are not there, according to the Durham University study.
‘High caffeine users’ – those who consumed more than the equivalent of seven cups of instant coffee a day - were three times more likely to have heard a person’s voice when there was no one there compared with ‘low caffeine users’ who consumed less than the equivalent of one cup of instant coffee a day.
4 Perspectives on Matthew 27.52-53 in face of this recent caffeine studies:
1) The author or source of that particular passage had too much coffee in the morning.
2) Jerusalem had a coca-cola competition on the previous night. The one who drinks most coke will received a free empty tomb as burial site for hes/her family. Oh.. that comes along with free ossuaries too.
3) There was a purification ritual of drinking 7 cups of coffee among 2nd temple Jews which we still haven't found the historical evidents for it yet. But the fact that number 7 being a perfect or complete number among them serves as a strong clue.
4) Ignore the caffeine research. The passage describes exactly what happened. Risen dead people went into Jerusalem and remain alive till now.
So, what's your perspective?
