Even if he is Christian; it's kind of strange to me that people don't realize that other cultures will use Western cultural references that might be very "heavy" in a different, much more casual way. I mean, Western companies talk about code "ninjas" all the time; and I have heard a few samurai and zen references too.

Japan talking about Christians isn't particularly different. Christianity and comparisons to it are made relatively casually, with much less cultural weight than they would have in the US or Europe. Here's a Japanese rap song [1] whose lyrics [2] go, "As the Bible is to a devout Christian, so to me is is the Zulu Nation" (translation [2]).

So in my opinion the "internet Jesus uses secret creed" thing is at least mildly clickbaity. It'd be the equivalent of seizing upon the name "Zen of Python" to write an article about "A Language with a simplicity driven by Buddhism".
