It is an unfortunate fact missionaries are many times required to return to home base due to a lack of resources. I cannot fault a missionary for this, but I do fault the church. Like those who give offense to little children, I think a millstone should be hung around their neck and they should be cast into the sea. Surrender the frontier. To follow our story, in 1278, the Pope sent 5 Franciscans, and by 1300 they were at work in 17 stations throughout the empire, with a monastery at Cambaluc.
Most missionaries resist the urge to retreat.
This is not to say that ministry among the Christians of World A countries isn't needed. Frontier missionaries cannot surrender that calling. We must constantly seek for new ways, options, possibilities, opportunities for creatively evangelizing the World A peoples of our planet. Fortunately, the Franciscans didn't make this mistake, and now we turn to the results of their labor. Cutting deals on the frontier.
