Gregory’s bull, as inserted in the canon law, provides perpetual imprisonment for those who “redire noluerint” (C. 15, § 1, Extra v. vii.), which is self-evidently an error for “voluerint,” as the previous section directs that persistent heretics are to be handed over to the secular arm. Besides, Frederic’s Ravenna decree, issued soon after, in prescribing lifelong imprisonment for converts, speaks of this being in accordance with the canons.
