Which, being translated, says to the people outside the Church that God runs a railway so badly that the bridge isn't properly interlocked with the home signals, SPADs happen regularly, and unauthorised persons are in places where they cause accidents. Please, if you are going to try to draw this sort of parallel, get the technology right. Or as someone else put it about a different version of the story.
"Then,one day, as he was about to close the bridge, he noticed that his son was playing in the gears. Should he close the bridge and crush his son to death, or leave it and have the train smash into the river? In the end he sacrificed his son to save the train. Now what does that tell you about God?"
Matt detonated. "That he's no b*****, sorry Reverend, no good at running a railway."
Stone's eyebrows rose.
"Firstly the home signals should have been interlocked with the bridge bolts so that he couldn't clear the signals for a train until the bridge was closed and locked. Secondly, assuming the interlocking was there the drivers shouldn't have approached the homes when they were on-"
"On?"Stone was trying to make sense of it all.
"Showing a red light for stop."
"Ah."
"Thirdly the drivers shouldn't have approached at a speed that didn't let them stop if the signals didn't clear. That's just asking for a spad."
"What's a spad?"
"Signal passed at danger. Railway equivalent of running a red light. Fourthly the gears should have been fenced. Anyway if the kid had any brains he'd not have been there, if his parents were competent they'd have supervised him properly, and human bone would probably jam the gears tipping the train into the river anyway."
"I see. I don't understand the technical jargon, not being a railway expert, but the point is to illustrate something about God, that he's prepared to sacrifice his son."
I cut in. "But he's been sacrificed to a monumental ******, not to achieve anything. Is that what you mean?"
I've bleeped the rude words, but please remember how this looks to someone outside the church who does know how to run a railway.
