In 1439 in Florence, the Declaration of Union was adopted, according to which "the Roman Church firmly believes that nobody, who does not belong to the Catholic Church, not only unbelievers, but Judeans (Jews), nor heretics, nor schismatics, cannot enter the kingdom of heaven, but all will go to the eternal fire, which is saved for devils and their angels, if they not before death turn to that church". The Council of Trent (1545–63) had the mission to gain, apart from "stray" Protestants, also the numerous "schismatics" in southeastern Europe.
