petrine

The adjective 'petrine' is a direct formation from the name 'Peter', which itself originates from the Greek word 'petros', meaning "rock" or "stone." This Greek term was famously used by Jesus in the New Testament when he declared, "You are Peter (Petros), and on this rock (petra) I will build my church," establishing a foundational metaphor. The suffix '-ine', borrowed via Latin, is a common adjectival suffix in English, as seen in words like 'canine' or 'divine'. Thus, 'petrine' literally means "pertaining to Peter," and its specific theological application evolved to describe doctrines, authority, or characteristics specifically linked to the Apostle Peter and, by extension, to the papal office which claims his succession.
