[Decree that there ought to be only one council]

The most holy general synod of Basel, legitimately assembled in the holy Spirit, representing the universal church, for an everlasting record. Just as there is only one holy catholic church, as Christ her spouse says, My dove, my perfect one, is only one, and as an article of the faith declares, since unity does not tolerate division, so there can be only one general council representing the holy catholic church. Since, therefore, by decrees of the sacred general councils of Constance and of Siena and by the approval of two Roman pontiffs, namely Martin V and Eugenius IV of happy memory, a general council was instituted and established in this city of Basel and assembled legitimately in the holy Spirit, it is clear that during this council another general council cannot exist elsewhere. Whoever therefore, during the lifetime of this sacred council shall presume to raise and hold another assembly with the title of a general council, is convicted of raising and holding a conventicle of schismatics and not a council of the catholic church. Therefore this holy council warns and exhorts all Christ's faithful, of whatever status or rank they may be, even if papal, imperial or regal, under the adjuration of the divine judgment which holy scripture relates in the case of Korah, Dathan and Abiram, authors of schism, and it strictly commands and forbids them in virtue of holy obedience and under the penalties laid down by the law, not to hold or summon, during this sacred council, another assembly with the title of a general council, which in reality would not be a council, nor to go to or to take part in or in any way to have recourse to it as if it were a general council, even under the pretext of any promise or oath, nor to hold or esteem it to be or even to call it a general council, even if it claims to have been summoned or shall try in the future to be summoned. If any ecclesiastical person, even a cardinal of the holy Roman church, or anyone else of whatever status, rank or condition he may be, shall dare to go to or stay in Bologna or any place with a pretended general council, during this present council, he shall automatically incur sentence of excommunication and deprivation of all benefices, dignities and offices and disqualification from them; and the dignities, offices and benefices of such persons may be freely disposed of by those to whom this pertains by law even if
