[Eugenius IV exhorts the members of the synod at Basel to desist from their opposition]

Eugenius, bishop, servant of the servants of God, for an everlasting record. In the opinion of holy fathers, public sinners ought to be publicly censured so that others may stand in fear. Accordingly, we and this sacred council of Florence recently censured and denounced in public before the church, in synodal form, the authors and abettors of the pestilential sin of schism against the holy apostolic see and the holy Roman church, the mother and mistress of all Christians, which was perpetrated by Amadeus, once duke of Savoy, and his accomplices. It would have been in conformity with the sacred canons to have passed a sentence of due severity straightaway on those notoriously sacrilegious persons. However, desiring their conversion and salvation rather than their punishment, we begged, warned and required of them, with all the charity and mildness we could, to reflect and to recoil from such great iniquity, promising them pardon and favour and a father's affection. But if they refused to heed these dutiful admonitions, we decreed that they should be punished with penalties proportionate to so great an outrage, as is contained in the monition promulgated against them, which is as follows.
