What does Senator Bird at first believe that the law is "right and Christian"?

Is this the section you're referencing?

“There has been a law passed forbidding people to help off the slaves that come over from Kentucky, my dear; so much of that thing has been done by these reckless Abolitionists, that our brethren in Kentucky are very strongly excited, and it seems necessary, and no more than Christian and kind, that something should be done by our state to quiet the excitement.”

“And what is the law? It don’t forbid us to shelter those poor creatures a night, does it, and to give ‘em something comfortable to eat, and a few old clothes, and send them quietly about their business?”

“Why, yes, my dear; that would be aiding and abetting, you know.”
