Pius Voting
Consequently, there is a heavy responsibility on everyone, man or woman, who has the right to vote, especially when the interests of religion are at stake; abstention in this case is in itself, it should be thoroughly understood, a grave and a fatal sin of omission.
On the contrary, to exercise, and exercise well, one’s right to vote is to work effectively for the true good of the people, as loyal defenders of the cause of God and of the Church.
– Pope Pius XII, Allocution to the Congress of the International Union of Catholic Women’s Leagues, Rome, Italy, September 11, 1947.
