You can literally buy one on the internet and learn that its not. The masonic bible in almost all the continental united states is the 1611 authorized KJV, with an added concordance in the back with textual references to the scriptures and historical stuff used in the ritual. This is all context for the building of the temple solomon allegory that is used in the blue lodge, or vanilla freemasonry.
That being said, I'm sure you will find some spoopy mystery allegory in plenty of masonic publications, especially if you are rooting around in the southern jurisdiction, which was Albert Pike's stomping ground back in the day.
Washington's quote in your post is also correct. While the overwhelming majority of US Masons are Christian, I'm sure you will find some who are not. It is explicitly a non-religious organization, and as I've iterated before, discussion of religion inside the lodge gets you expelled. The only requirement everywhere except France is that you have to profess a belief in a deity of your choice, otherwise you are a flake and your word doesn't mean anything.
This is different in the York rite. The last 4 degrees of it (out of 10 I think, in contrast to the Scottish rite which has 33) require you to profess a belief in the God of the old testament and in his son Jesus Christ as the redeemer of mankind. This is made most evident in the ritual of the Masonic Knights Templar and the Red Cross of Constantine, which are the last degrees of the York Rite appendant body. Before the conspiracy nuts go wild, no, the Masonic Knights Templar has nothing to do with the crusader order disbanded and persecuted in 1307. This degree began in the early 1900s among York rite masons in the northeastern US.
Further evidence of the York rite being an explicitly Christian subset of speculative masonry is also present in the funeral service of the Masonic Knights Templar. The full text of this service is also available online.
Some excellent books on masonry that aren't tainted by conspiracy nuts and other habitual exaggerators include "Pilgrim's Path" by John J Robinson and "Born in Blood" by the same. He's a historian, a non-mason, and a non-catholic, and I feel he gave it all a pretty fair shake.
There's a lot to unpack on the subject, especially for people who don't really bother to learn about it outside of that book Pat Robertson put out back in the 80s or 90s. A lot of modern anti-mason stuff comes directly from that dude.
