You have been quoting the surviving church fathers, thus suffering from survivor bias. These are the ones whose teachings were not a danger to church doctrine. You have neglected to take into account the character of the church that emerged from their destruction knowledge - it has nothing to do with the love that Jesus taught. By looking at what they destroyed from Origen’s Commentary on the Gospel of John, we can gain insight into what they found objectionable to their doctrines of the trinity and eternal damnation.
For me, the most important thing about the remaining fragments of the 32 books on John is what is missing. The first ten books went from John 1:1 to 2:25, but what was destroyed by the Roman Empire was John 1:8-14, 1:30-51, and 2:1-11. We have enough evidence of Origin’s unique insight to know that what he wrote about the baptism of Jesus, the second coming of Elijah, and Jesus’ turning water into wine in Cana posed grave danger to the dogma created by the Roman Empire.
Ronald Hein continued his valuable work on the second half of Origen’s Commentary on John. As one of the last of Origen’s works, it is, in my opinion, the most important for our world today. This book is rare since it is translated from his original Greek and not from a Latin dogma-adjusted summary.
This book provides great insight into the logic that Origen used in his analysis of the entire text of the bible – comparing the same phrase’s meaning at each occurrence and weighing the most reasonable meaning, while providing the reader with his analysis. Thanks to Mr. Heine, modern researchers have access to the enlightened period that existed before the Dark Ages.
Again, the second half of the fragments provides a clear picture as to what the materialistic rulers of Rome feared in Origen. The commentaries on the most controversial chapters were destroyed – chapters 3,4,6,7,9,10,12. In addition, the following sections are also missing 4:1-12, 8:1-18, 8:26-36, and 11:1-38.
So, no one can say what Origen taught about reincarnation can be read out of the remaining teachings, since this was the most dangerous to the slave-state of Rome. You cannot threaten eternal damnation to a person who believes in reincarnation.
