I will look more at citations, but they are not easy. Most of the Jesus side is directly from the Gospels. some items still don't have chapter and verse, but
many do and more will.

Paganism is a massively "distributed" movement with very few widely recognized references or authorities, but with well and widely understood principles. The one book I do reference, Godless Paganism, is very good, being composed of many short pieces by at least 30 non-theist Pagans of every stripe imaginable. Most Pagan literature is short pieces, just as early Christian literature was.

Paganism is held together mainly by the Internet. There are Web sites like Patheos, and magazines like Witches and Pagans. These publications tend to be a bit "Witchy", but that's the largest contingent. Lots of Witches write for their own, predominantly women refugees from Evangelical and other repressive churches.

Wicca is a semi-organized group ritual religion. It is supposedly (but not actually) based on ancient Celtic witchcraft, but no longer likes to be called "witches". "Witch", on the other hand, is a calling, mostly solo practitioners who cheerfully accept the term "witch" and re-conceptualize it.

By far, the majority of Pagans of all stripes are solo practitioners, belonging to no organization - though Pagans are now estimated to outnumber Presbyterians.

My descriptions of the Gospels would be hard to cite, as these sections are my own compilation from the opinions of literally dozens of biblical scholars. Much can be found in Wikipedia, but I also use other sources intermingled, particularly articles in Biblical Archaeology, and include my own direct reading of the Gospels.

Yes, I know - Wikipedia doesn't consider "original research" to be an acceptable citation.
