Earlier quoted context omitted.
>this world is fallen Makes the entire article essentially meaningless. How can I trust somebody with such a bizarre and unconnected worldview?
It's a mistake to process these ideas on the basis of trust. True, the religious angle is shoehorned at the end. But the author cites secular books and ideas throughout; these ideas and the relationships between them are worth considering.
Now, imagine you haven't read the article, somebody comments, "This guy said the earth is flat!" and you ctrl+f into the article and they did, in fact, write that. Should you be encouraged to read the article? They have some secular studies and ideas.
