I'm not sure if my comment is getting replaced by the mods after I edited it or not, so I'm just reposting sans the amazon product mod, because... whatever.
Christian deism or the Jefferson Bible?
Srsly, both are basically a Google search away.
EDIT: I know I get irritated when people ask for primary sources and give some obnoxious 'just google it' response, but that generally when talking about contemporary news stories, whereas the founding fathers' deistic beliefs is pretty well-established historical fact. I also did a lot of this reading \~ a decade ago
BUT here's what I can try to give you:
​
* Wikipedia is great for these and has good primary sources (obviously I'm not going to list them all)
* [Christian Deism](https://en.wikipedia.org/wiki/Christian_deism)
* [The Life and Morals of Jesus of Nazareth](https://en.wikipedia.org/wiki/Jefferson_Bible) by T. Jefferson, aka the "Jefferson Bible"
* The text of the Jefferson Bible is totally available (apparently I can't link to amazon...). The Smithsonian apparently created a [full-color recreation of the original text](https://www.amazon.com/Jefferson-Bible-Smithsonian-Morals-Nazareth/dp/158834312X) a little less than a decade ago.
* [This](https://enlightenmentdeism.com/christian-deism/) is a reasonable blog post that appears to discuss the broad spectrum of deistic beliefs, though the single paragraph style is a bit overwhelming.
* Here's a [WaPo](https://www.washingtonpost.com/news/acts-of-faith/wp/2017/06/28/how-benjamin-franklin-a-deist-became-the-founding-father-of-a-unique-kind-of-american-faith/) article about Benjamin Franklin's deism (though I think he converted to more orthodox beliefs later in life).
* Encycopaedia Britannica has an entery on "[The Founding Fathers, Deism, and Christianity.](https://www.britannica.com/topic/The-Founding-Fathers-Deism-and-Christianity-1272214)"
* Another encyclopedia entry of middling quality is [here](http://www.humanreligions.info/deism.html). Some of the citations aren't very good.
​
Overall, I think the wiki articles are the best.
Don't hate on Jesus, even Jefferson so potential in a person with good intentions: https://www.amazon.com/Jefferson-Bible-Smithsonian-Morals-Nazareth/dp/158834312X/ref=pd_sbs_14_t_0/137-8229286-4014834?_encoding=UTF8&pd_rd_i=158834312X&pd_rd_r=026db146-55ee-4501-afda-bb9c85c7cf81&pd_rd_w=2P2nc&pd_rd_wg=rMtNZ&pf_rd_p=5cfcfe89-300f-47d2-b1ad-a4e27203a02a&pf_rd_r=A0ZWKTDSZ77J7CP4R6HB&psc=1&refRID=A0ZWKTDSZ77J7CP4R6HB
