Gospel Guidebook: Getting and Keeping It Right 
한국어 日本語
Introduction
As stated in my core beliefs, I believe in the Oneness of God (aka Modalistic Monarchianism). In particular, I believe in a strict Monotheism – that God is numerically one. I believe that the one God of the Old Testament, YHVH, became a man in the person of Jesus Christ. Jesus, the Son of God, is both fully God and fully man, being the visible image of the one invisible God. Jesus' deity is none other than that of the Father. As it pertains to His humanity, Jesus was born of a virgin in time.
I don't plan on writing much about Oneness, but I have provided some links below to books, articles, and videos I have found helpful. I have also archived some of the writings of Steven Ritchie from the Wayback Machine. He was a Oneness Pentecostal apologist who passed away in 2022. I found his writings helpful, but his website was suddenly taken down in early 2023. I am not a Pentecostalist, and I strongly object to his teaching on baptismal regeneration (i.e., salvation through water baptism), but he has contributed much to defending Oneness, and I think his writings should be available to people studying this topic.
Oneness
Books
The Oneness of God by David K. Bernard (This is basically the standard textbook for Oneness theology.)
The Case for Oneness Theology by Steven Ritchie (This ebook was available for $10 on Ritchie's website. I bought it just a few days before his website was suddenly taken down, so the timing might have been providential. This ebook is copyrighted and I provide it for reference purposes only so that Ritchie's work can remain available. If you are interested in purchasing this ebook or a paperback version, please try to contact theglobalimpactministries@gmail.com. As I mentioned above, I don't believe in "baptismal regeneration," so I can't recommend everything in this book, but in terms of Oneness theology, it is very helpful.)
