What does Miss Maudie have to say about Atticus?

According to Miss Maudie, Atticus' courage and integrity makes him an admirable man. She tells Jem that Atticus has taken on the mantle of a true Christian: he is defending an innocent black man from being convicted for a crime he didn't commit.
In Miss Maudie's conversation with Jem, she tells him what she most admires about Atticus: his belief in equality for everyone. Atticus' principles can be summed up in the following quote:

“But there is one way in this country in which all men are created equal—there is one human institution that makes a pauper the equal of a Rockefeller, the stupid man the equal of an Einstein, and the ignorant man the equal of any college president. That institution, gentlemen, is a court...Our courts have their faults, as does any human institution, but in this country our courts are the great levelers, and in our courts all men are created equal."

During her conversation with Jem, Miss Maudie tells Jem that Atticus has more supporters than most people realize. She maintains that Judge Taylor's naming of Atticus as Tom Robinson's court-appointed lawyer was no accident. By right, Tom's case should have gone to Maxwell Green, Maycomb's newest lawyer. However, Judge Taylor named Atticus because he knew that Atticus was the only lawyer who could come close to saving Tom.
Most importantly, Judge Taylor knew that Atticus was the only lawyer who could tweak the public's conscience about the travesty of justice Tom has suffered.
Later, Miss Maudie tells Aunt Alexandra that, by letting Atticus represent Tom, Maycomb was paying the highest tribute they could pay to a man. Essentially, the public trusted Atticus to do what was right in the eyes of the law. Miss Maudie also maintains that Atticus has his supporters: people who believe that fair play is for everyone.

Following the Tom Robinson trial, Miss Maudie reveals her support for Atticus and his family by baking the children cakes. When Jem, Scout, and Dill visit Maudie's home to eat their cakes, Miss Maudie encourages Jem not to fret. She then says,

I simply want to tell you that there are some men in this world who were born to do our unpleasant jobs for us. Your father’s one of them (Lee, 219).

Miss Maudie understands the difficult task that Atticus faces while defending Tom Robinson in front of a prejudiced jury. Unlike the racist majority of Maycomb's citizens, Miss Maudie does not attend the trial and simply wishes Atticus the best.
Maudie then proceeds to tell Jem that the community of Maycomb is fortunate to have a brave, morally upright man like his father to represent them when they are called to be Christians. Maudie finishes her conversation by elaborating on the numerous people in the community who supported Atticus's efforts defending Tom Robinson.
