The US Conference of Catholic Bishops releases a document every 4 years, called Faithful Citizenship, which reminds US Catholics of their rights, responsibilities and duties with respect to engaging in civic life.
From the Bishops’ Website:
We urge our pastors, lay and religious faithful, and all people of good will to use this statement to help 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. The statement lifts up our dual heritage as both faithful Catholics and American citizens with rights and duties as participants in the civil order.
