"these words of Paul"
Horace by Anton von Werner
Public DomainHorace by Anton von Werner

The quotation is from St Paul's first letter to Timothy (4:12).

Given the rule-bound nature of St Paul's teachings, he makes a strange contrast with the Roman poet Horace, who wrote the next lines Hardy quotes. Known for phrases such as "carpe diem" and "dulce et decorum est pro patria mori", Horace espoused an ideal of enjoying the moment and getting the most out of the here and now.
