‘One of themselves’ – this is talking about the inhabitants of Crete. This is a Epimenides who was a Cretan wise man and poet of about 500 BC.
Just stick with the liars. This is a society of lies, isn’t it? Lies in business, lies in the banks, lies wherever you look. Excuses which are half true, sick notes that aren’t genuine, false expense claims, petty lies, grotesque lies. It’s a world of lies. It gets into the church too – ridiculous Charismatic exaggerations, the spirit of the lie. The Cretans are always liars.
