The series Conciliorum oecumenicorum generaliumque decreta publishes critical editions of the decrees of those church councils which are termed ‘ecumenical’, as well as those of the main ‘general’ councils whose authority is recognized by most Christian denominations, or are accorded such status within the Roman tradition.

Canonical reception, theological effect, the scholarly consensus are therefore applied as the main criteria of a work based on scientific parameters and on philological principles. However, as well as each scholar who needs definitive editions, also the theologian can trace the proper approach of his discipline and confession.

When finished, the series will consist of seven volumes, spanning almost two millennia of conciliar decrees, all of them critically edited, indexed and introduced by specialists. This unprecedented research program is conducted under the direction of Giuseppe Alberigo i.m. and Alberto Melloni.
