Pope John approved the Code of Rubrics by the motu proprio Rubricarum instructum of 25 July 1960.
Decretorum (Additions and alterations to the Rubrics of the Missal in line with the Bull Divino afflatu and the decrees of the Sacred Congregation of Rites that followed it).

Simplifications included elimination of many of the patristic readings at Matins and a reduction in the number of commemorations to be observed in the Office and Mass.
