There are literally dozens of books you can choose to study if you wish. The fact is, scholars have been writing on this for
centuries.
Edit- link did not work properly, Google:
"In search of truth Augustine, Manichaeism and other gnosticism"
You can find this book online.
What I am asking for is for you to make your case citing your sources. Posting a link to some book with some vague claim is not helpful.
