My great-grandmother was a very staunch Christian, a Presbyterian to be exact. She took the “Great Commission”* quite seriously and was known for proselytizing whenever and wherever she could. I am not aware that she ever left the US, and she spent nearly all her time in the Southeast to boot, but she may have saved a few souls here and there.
[*“The Great Commission” is Jesus’s command to his disciples to convert everybody, often expressed in the form found in Matthew: “Go and make disciples of all the nations.” Been referred to above but I’m not sure it’s been named.]
Great-grandmother was also of the opinion that everybody, everybody on earth had the chance to learn about Christianity…that was just how Jesus rolled. Each person, no matter who, had at least one encounter with Christian thinking, and if he or she latched on to it, well and good, if not–Thus, there were in her book no people who had never heard of Christianity, thus no one was ever let off the hook.
This was, to put it bluntly, an insane way to look at the world. My grandmother, her daughter-in-law, tried challenging her on the subject once. “Well, now,” she said, “what about a person in a far-off part of a country where missionaries have never set foot?”
So great-grandmother told her a story she had heard (in church, natch) about a man in China, a simple fellow who lived far from the beaten path, and how he had never heard of Jesus or the Christian God, till the day he happened to buy some fish at the local market, and the fishmonger wrapped the fish in some newspaper that was lying around, and when the man got home he noticed that it was an evangelistic paper in the Chinese language, and, well, he read it and became a Christian, because Jesus gave him a chance…
“Do you mean to tell me,” my grandmother demanded, “that that poor man would have gone to hell on account of a newspaper, if he hadn’t had the time to read it?”
I think the answer was “God moves in mysterious ways,” or something similar, and Grandma rolled her eyes and never brought up the subject with her mother in law again.
