Quote #7
But what vexed me most was his saying that every man should be master of himself. If I knew anything it was that all men belonged to someone. Surely God Himself put us all in our places: Lords to rule and fight. Clergy to pray. All the rest—like me—were on earth to labor, to serve our masters and our God. (24.61)
Crispin's referring to what is sometimes called the "Three Estates" of Medieval society—those who work, those who fight, and those who pray. While the reality was significantly more complicated, this was a simple way for people to explain their place in society to themselves and others.

"Crispin," she said. "whatever noble blood there is in you, is only… poison. Lady Furnival, who's the power here, will never let you have the name. She'll look on you as her enemy, knowing that anyone who chooses to oppose her will use you and what you are." (49.38)
Being a noble isn't always all it's cracked up to be. Sure, Crispin is the son of Lord Furnival, but really powerful people are willing to kill him to make sure he's not a threat to them, and anyone who would help him is probably just using him to help themselves. So yeah, not automatically awesome.
Quote #9
"Your connection gives no honor. No position. What someone fears is not you, but that you will be used. Can't you see it? Your noble blood is the warrant for your death. It will remain so till it flows no more." (49.46)
Okay, thanks, Widow Daventry. We get the point: Noble blood equals death warrant. Historically speaking, she's not wrong. A lot of people were killed because they could make a claim to wealth or position someone else wanted.
