Lines 495-510: What is the central claim of this paragraph? What reasons and evidence does he have to support it?

I'm sorry, I do not know what paragraph is in question.

have watched so many churches commit themselves to a completely otherworldly religion which made a strange distinction between bodies and souls, the sacred and the secular. There was a time when the church was very powerful. It was during that period that the early Christians rejoiced when they were deemed worthy to suffer for what they believed. In those days the church was not merely a thermometer that recorded the ideas and principles of popular opinion; it was the thermostat that transformed the mores of society. Wherever the early Christians entered a town the power structure got disturbed and immediately sought to convict them for being "disturbers of the peace" and "outside agitators." But they went on with the conviction that they were "a colony of heaven" and had to obey God rather than man. They were small in number but big in commitment. They were too God-intoxicated to be "astronomically intimidated." They brought an end to such ancient evils as infanticide and gladiatorial contest.
