The Decree
In the name of the Holy and indivisible Trinity; of the Father, Son, and Holy Ghost. Amen.
A frequent celebration of general councils is an especial means for cultivating the field of the Lord and effecting the destruction of briers, thorns, and thistles, to wit, heresies, errors, and schism, and of bringing forth a most abundant harvest. The neglect to summon these fosters and develops all these evils, as may be plainly seen from a recollection of the past and a consideration of existing conditions.
Therefore, by a perpetual edict, we sanction, decree, establish, and ordain that general councils shall be celebrated in the following manner, so that the next one shall follow the close of this present council at the end of five years. The second shall follow the close of that, at the end of seven years, and councils shall thereafter be celebrated every ten years in such places as the pope shall be required to designate and assign, with the consent and approbation of the council, one month before the close of the council in question, or which, in his absence, the council itself shall designate. Thus, with a certain continuity, a council will always be either in session, or be expected at the expiration of a definite time. This term may, however, be shortened on account of emergencies, by the supreme pontiff, with the counsel of his brethren, the cardinals of the holy Roman Church, but it may not be hereafter lengthened.
The place, moreover, designated for the future council may not be altered without evident necessity. If, however, some complication shall arise, in view of which such a change shall seem necessary, as, for example, a state of siege, a war, a pest, or other obstacles, it shall be permissible for the supreme pontiff, with the consent and subscription of his said brethren, or two thirds of them, to select another appropriate place near the first, which must be within the same country, unless such obstacles, or similar ones, shall exist throughout the whole nation. In that case, the council may be summoned to some appropriate neighboring place, within the bounds of another nation. To this the prelates, and others, who are wont to be summoned to a council, must betake themselves as if that place had been designated from the first. Such change of place, or shortening of the period, the supreme pontiff is required legitimately and solemnly to publish and announce one year before the expiration of the term fixed, that the said persons may be able to come together, for the celebration of the council, within the term specified. . . .
Note on the excerpt
Robinson's printed text is an abridged excerpt: it ends with an ellipsis, and this footnote summarizes the omitted tail — the portion of the decree concerning John XXIII, who had fled from Constance. The council claims that John enjoyed full liberty at Constance, and orders that he shall not induce the cardinals and members of his curia to desert the council and follow him.
