‘the Ford’ when they meant ‘the car’, even if in fact it was a Volvo. Something similar has happened with the word ‘Pentecost’. If ‘Pentecost’ means anything at all to most people today, it is probably something to do with ‘Pentecostalism’. And that—again, if it means anything to people at all—probably signifies a somewhat wild form of Christian religious experience and practice, outside the main stream of church life, involving a lot of noise and waving of arms, and (of course) speaking in tongues.
