Soon after the end of the council, theologians tended to split into two general groups, with a more conservative party stressing a return to the patristic and scriptural sources ("ressourcement") and a close and literal reading of the conciliar documents in contrast with another party stressing to some extent the continuation of "aggiornamento" and certain amount of extrapolation from the documents. This split remains to this day, and is a key division on "Dignitatis humanae". Some commentators still continue to try to show that the document is fully consistent with the 19th-century papal statements on these issues.
