Pope John XXIII announces that no Roman Catholic is permitted to vote for any person, party, or measure that supported communism in any way. This is the first time the Vatican has ever instituted a blanket ban on voting for or supporting any political party. Not even the Nazi Party has ever been treated this way.
According to the new decree, Catholics may not vote
"for parties or for candidates who, even if they do not profess principles in contrast to Catholic doctrines, or even the attributes of Christianity, may unite with communism or aid the Communists."
"Read the decree and you form an idea of the sad duties to which Catholic universalism is reduced. Read it and learn that today we Communists are not alone among the excommunicated... But with us are linked all those parties or candidates which, although Christian or Catholic, give us de facto support."
