Lines 497–510: What central claim does King make in this paragraph? What reasons and evidence does he use to support it?

"Yes, these questions are still in my mind. In deep disappointment I have wept over the laxity of the church. But be assured that my tears have been tears of love. There can be no deep disappointment where there is not deep love. Yes, I love the church. How could I do otherwise? I am in the rather unique position of being the son, the grandson and the great-grandson of preachers. Yes, I see the church as the body of Christ. But, oh! How we have blemished and scarred that body through social neglect and through fear of being nonconformists.

There was a time when the church was very powerful—in the time when the early Christians rejoiced at being 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 a thermostat that transformed the mores of society. Whenever the early Christians entered a town, the people in power became disturbed and immediately sought to convict the Christians for being “disturbers of the peace” and “outside agitators.” But the Christians pressed on, in the conviction that they were “a colony of heaven,” called to obey God rather than man. Small in number, they were big in commitment. They were too God-intoxicated to be “astronomically intimidated.” By their effort and example they brought an end to such ancient evils as infanticide and gladiatorial contests."
