John Claudius Pitrat 
Pagan Origin of Partialist Doctrines [PDF ebook] 

The religious belief of partialism states that not everyone will achieve salvation in God’s eyes. Because they subscribe to the notion of hell and eternal damnation, many Christian denominations can be said to hold to the doctrine of partialism. In this book, theologian John Claudius Pitrat contends that this belief system is actually a holdover from pagan times and does not reflect the true nature of Christianity.
