The Catholic Church is not a political party, and its teachings are not a political platform.
The Church has authority in political matters, but only when politics invades its territory. That territory is in the realm of the eternal. The unchanging truths about the dignity of mankind and the meaning of human life.
Outside of those teachings, the Catholic Church leaves us free to discern what is best in our political environment and even to arrive at diverse political conclusions on all but just a few immutable “life” issues.
Because of this, we need to approach politics and voting with a clear conscience.
The only way to do this is by obtaining a clear understanding of the unwavering truths the Christian faith teaches about human beings and society.
