Pardon the anachronisms: neither the Colosseum nor weekends* were a thing in Paul's time.
*It's nuanced: the two day weekend during the seven day week that would have been familiar to JWs in 1961 didn't yet exist.
1961? Millions then living are now dead! Note the urgency about the New World Society.
Interesting side note: New World Supermarkets were a chain in Australia in the 1960s. Coincidence? I think not!
