James McMullen Rigg, Dictionary of National Biography… (1912)
“ The truth of revelation being thus 'not the truth of theological statement, but that of fact and experience,' it is, in Tyrrell's view, 'a patent fallacy to speak of a "development" of revelation as though it were a body of statements or theological propositions,' and the sole legitimate function of theology is ' the protection and preservation of revelation in its original form and purity.' Even to the dogmatic decisions of councils he therefore allows only a 'protective' value, as reassertive, by no means as ampliative. ”
