A clever quip, but I have to point out that most adherents for a given ideology have never actually read the canonical text of their ideology. The Bible particularly was generally inaccessible to laypeople for a ~1000 year period, who would typically learn everything they knew about it filtered through the preachers of the Church. Even today with easy access, a majority of Christians have not read it.
So the "employees" of X are untrustworthy, but the collection of circular letters for the "employees" of X is not. This doesn't make any sense.

Depending on the denomination, 50% to 100% of the service they do revolves around reading from that book.

Also what do you understand by "the Church".
The Bible was fairly widely read, but books were very expensive until the invention of printing. There were efforts - it would have been read to people, there were English translations of parts of it going back to the 7th century. Reading it aloud forms a large chunk of services even today.

Not read all of it certainly. However, most Christians have definitely read some of it. The Bible is not "the canonical text" for two reasons: there are disagreements about what is canonical, and it is not a single text, it is a collection of works.
Not reading all of it - why should we? What is the point of Christians reading things such as (most of?) Leviticus which is a collection of rules that do not apply to Christians? It is perfectly reasonable to be selective about which books within a large collection people read.
