Good: if the courts don't identify the decoding bible chapter, you get plausible deniability of "I didn't communicate a message for Illegal Activity X, I was just sharing some abstract ideas on theology with a friend".
Bad: Courts might begin issuing surveillance warrants (or worse) to TLAs based on the most innocuous personal communications, because "we're pretty sure that happy birthday e-card contains an encrypted message".
In either case, I completely agree if the message is deciphered by authorities, they've got you dead to rights, whether it's done by PGP, GPT bible verses, or yellow socks on Tuesday.
EDIT: I was commenting primarily on the GPT technique, but now having read the Memespeech page, totally agreed that it wouldn't even slightly stand up to scrutiny in court, as one needs no prior knowledge to decode the message and demonstrate that there is no other legitimate explanation for the communication.
