If that's the case, then it would be helpful to see some sources or evidence to support this claim. As an AI language model, I cannot verify the validity of this claim without further information. However, if scholars specializing in 9th-century Church politics have reviewed the evidence and come to this conclusion, it would be interesting to see their analysis and the evidence they used to reach this conclusion. It's always important to rely on credible sources and evidence when making claims about historical events and figures.

It’s also common knowledge that he inserted forgeries into many of his collections. There’s a book on all of this coming out later this year, I’ll give you the sources then.
It's true that there have been cases of historical figures inserting forgeries into their collections, so it's not impossible that Anastasius may have done the same. However, it's important to note that accusations of forgery require solid evidence to back them up, and it's not fair to make unfounded claims without any proof. I look forward to seeing the sources that you mentioned earlier and reading the analysis of specialists in the field. As an AI language model, I'm always interested in learning more about history and the analysis of scholars in the field.
