As U.S. Catholics prepare to vote in the November election, the United States Conference of Catholic Bishops (USCCB) draws attention to its statement Forming Consciences for Faithful Citizenship: A Call to Political Responsibility from the Catholic Bishops of the United States. This year, the bishops have provided new resources for clergy, to assist them in preparing their parishioners to vote.
As Catholics, we are called to act as responsible citizens and participate, each in our own way, in political life to promote the common good. This is to be done with a properly formed conscience guided by Church teaching.
