Questions: I. Whether the substantial observance of days of penance, which is declared to be of grave obligation in the dispositive part of the Constitution Paenitemini, II, § 2, of 17 February, 1966, refers to the individual days of penance which are to be observed as a matter of obligation in the whole Church;
II. Or does it refer rather to the whole complexus of penitential days to be observed with the penances attached to them.
Replies: The S. C. of the council replied, with the approval of the Supreme Pontiff Paul VI:
I. In the negative.
II. In the affirmative; that is, one sins gravely against the law, who, without an excusing cause, omits a notable part, quantitative or qualitative, of the penitential observance which is prescribed as a whole.
Given at Rome 24 February 1967."
