Definition of peritus in English:



  • A theological adviser or consultant to a council of the Roman Catholic Church.

    • ‘They also consulted widely with non-Catholic observers and theological experts (periti), many of whom were also active in drafting council documents.’
    • ‘I noticed how he became more cautious in his embrace of the principles he had espoused as a peritus at Vatican II.’
    • ‘Any professor of theology, especially if he had been a peritus or ‘expert’ at the Council, was now an authority.’
    • ‘The perhaps equally numerous periti (experts and consultants who included some of the world's greatest scholars) were even more disadvantaged.’
