In 1396 Benedict sent Sanchez Muñoz, one of the most loyal members of the Avignon curia, as an envoy to the Bishop of Valencia to bolster support for the Avignon papacy in Spain.
Benedict, on the other hand, refused to stand down, so he was declared a schismatic and excommunicated from the Catholic Church by the Council of Constance on July 27, 1417.
Benedict should not be confused with the Roman Pope BenedictXIII, who reigned from 27 May 1724 to 21 February 1730.
Finally, BenedictXIII, by a decree of the 25th of September, 1756, ordered as of precept (in which consists the equipollent canonization) that throughout the Church the office and the Mass of Saint Gregory VII should be celebrated on the 25th of May, as a double.
BenedictXIII, on succeeding to the pontificate, availed himself of an intimacy formed with Cardinal de Noailles during the conclave in which Innocent XII was elected, and since maintained, to induce that cardinal to withdraw his opposition to the bull Unigenitus.
Benedict decided that the Catholic king would never be inclined to allow improper comedies to be performed in his dominions, and absolved the inhabitants from their vow, on condition of their giving an alms to the poor of not less than five hundred dollars.
