I mean, that could be the case, but for the record, they really seem like some seriously dedicated folks—a 1:590 ratio of code to tests! What is this, the Oracle test suite?—that is, dedicated in both in their work and their faith.

[...] according to the original author of SQLite and its main administrator, D. Richard Hipp, he received "100 per cent buy-in from all committers prior to publishing [the CoE]."

Hipp [...] defends the "Christian values" that the document represents and points out that SQLite source code has a "blessing" at the top of each file in place of a license and includes the Jesus-inspired phrase: "Find forgiveness for yourself while forgiving others."

"I could have edited the list down to just those aspects that seem relevant to coding," Hipp told us. "But that would put me in the position of editing and redacting Benedict of Nursia, as if I were wiser than he. [...] In the preface, I tried to make clear that the introspective aspects could be safely glossed over."

"Nobody is excluded from the SQLite community due to biological category or religious creed," he told us. "[...] The only way to get kicked out of the SQLite community is by shouting, flaming, and disrespectful behavior. In 18 years, only one person has ever been banned from the mailing list."

I find it more likely that they're just religious. To each their own.
