Taken from Photius' Bibliotheca
"Read Origen's four books On First Principles. The first deals with the Father, the Son and the Holy Ghost. In this his statements are often blasphemous; thus, he asserts that the Son was created by the Father, the Holy Ghost by the Son; that the Father pervades all existing things, the Son only those that are endowed with reason, the Holy Ghost only those that are saved. He also makes other strange and impious statements, indulging in frivolous talk about the migration of souls, the stars being alive, and the like. This first book is full of fables about the Father, Christ (as he calls the Son), the Holy Ghost, and creatures endowed with reason. In the second book he treats of the world and created things. He asserts that the God of the Law and the prophets, of the Old and the New Testament, is one and the same; that there was the same Holy Spirit in Moses, the rest of the prophets, and the Holy Apostles. He further discusses the Incarnation of the Saviour, the soul, resurrection, punishment, and promises. The third book deals with free will; how the devil and hostile powers, according to the Scriptures, wage war against mankind; that the world was created and is perishable, having had a beginning in time. The fourth book treats of the final end, the divine inspiration of the Scriptures, and the proper manner of reading and understanding them."
