What causes scout to question "pulpit gospel"? How does your questioning relate to Miss Maudie

From the text:

Apparently deciding that it was easier to define primitive baptistry than closed communion, Miss Maudie said: "Foot-washers believe anything that’s pleasure is a sin. Did you know some of ‘em came out of the woods one Saturday and passedby this place and told me me and my flowers were going to hell?"

"Your flowers, too?"

"Yes ma’am. They’d burn right with me. They thought I spent too much time in God’s outdoors and not enough time inside the house reading the Bible."

My confidence in pulpit Gospel lessened at the vision of Miss Maudie stewing forever in various Protestant hells. True enough, she had an acid tongue in her head, and she did not go about the neighborhood doing good, as did Miss Stephanie Crawford. But while no one with a grain of sense trusted Miss Stephanie, Jem and I had considerable faith in Miss Maudie. She had never told on us, had never played cat-and-mouse with us, she was not at all interested in our private lives. She was our friend. How so reasonable a creature could live in peril of everlasting torment was incomprehensible.

In observing Miss Maudie, Scout comes to question "pulpit gospel". She sees Miss Maudie as genuine, kind, understanding, and without hypocrisy.... unlike those who condemned her for enjoying her life.
