Tumors the Size of Apples..Yum?

I just read Boccaccio's Introduction to "The Decameron" and I have to say that I was disgusted and intrigued at the same time. As a fan of history, I found the author's depiction of the epidemic in Florence, Italy riveting. At first it seemed to me to just be a short historical commentary on the disease and it's affects on the city, but as I read further I felt the author was screaming at questions of morality. Multiple times it almost seems like Boccaccio is saying that the people of Florence deserved the Plague. As the naive person I am, I would like to say that God would not inflict this sort of pain on people, but Boccaccio has a point, as Ephesians 5:1-7 put it in the Bible:

"Therefore be imitators of God, as beloved children. 2 And walk in love, as Christ loved us and gave himself up for us, a fragrant offering and sacrifice to God.

3 But sexual immorality and all impurity or covetousness must not even be named among you, as is proper among saints. 4 Let there be no filthiness nor foolish talk nor crude joking, which are out of place, but instead let there be thanksgiving. 5 For you may be sure of this, that everyone who is sexually immoral or impure, or who is covetous (that is, an idolater), has no inheritance in the kingdom of Christ and God. 6 Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience. 7 Therefore do not become partners with them"

It's a little harsh but scripturally it's accurate. So say you are a non-religious person, which is 100% okay (freedom of religion, go America!) Boccaccio also has you covered. In the third paragraph of the reading he makes a jab at the physicians and medical practices in general, saying they were either unqualified or there was no cure out there. From every angle it seems Florence was just S.O.L!! I personally, as a Christian and a believer in the natural order of things, think that every epidemic, natural disaster, etc are a mixture of divinity and science, and while we can piece together the who's, what's, when's, and where's of almost any catastrophe, we can't answer the the biggest question, why.
