Reddit mentions of History of Christianity: The First Three Thousand Years

I'm a novice myself, and I'll admit to not having read the entire book, but "Christianity: The First 3000 Years" might have what you are looking for.

>A product of electrifying scholarship conveyed with commanding skill, Diarmaid MacCulloch's Christianity goes back to the origins of the Hebrew Bible and encompasses the globe. It captures the major turning points in Catholic, Protestant, and Orthodox history and fills in often neglected accounts of conversion and confrontation in Africa, Latin America, and Asia. MacCulloch introduces us to monks and crusaders, heretics and reformers, popes and abolitionists, and discover Christianity's essential role in shaping human history and the intimate lives of men and women. And he uncovers the roots of the faith that galvanized America, charting the surprising beliefs of the founding fathers, the rise of the Evangelical movement and of Pentecostalism, and the recent crises within the Catholic Church. Bursting with original insights and a great pleasure to read, this monumental religious history will not soon be surpassed.

While searching for it just now, I notice they have done a video called "History of Christianity", which is also available on Netflix.
