I can see that the text you've given me, labeled 'My text,' is entirely about Saint Peter, the apostle from the Bible, detailing his life and role. It doesn't, however, contain any information about a person named Peter Madrigal or any details related to net worth or finances. To create a comprehensive and accurate blog post about 'Peter Madrigal net worth,' as you've asked, I would need specific information pertaining to that individual and their financial background. The current text about Saint Peter does not provide the necessary context for such an article.
