As Catholics, before we vote, we are called to inform ourselves about the issues and to form our consciences correctly in accordance with the natural moral law and the teachings of the Catholic Church.
The Catholic bishops of the United States urge pastors, lay and religious faithful, and all people of good will to form their consciences; to teach those entrusted to their care; to contribute to civil and respectful public dialogue; and to shape political choices in the coming election in light of Catholic teaching. We have a dual heritage as both faithful Catholics and American citizens with rights and duties as participants in the civil order.
So let us inform ourselves, correctly form our consciences and vote accordingly.
Very Rev. John Lankeit preached a homily on October 2 at Ss. Simon and Jude Cathedral in Phoenix, Arizona that gives a Catholic perspective on the issues of the 2016 election.
