Priesthood and vocation · Question 9
“Priests aren't supposed to talk politics — so why do they wade into social issues?”

The question: “When they talk about elections, the economy, and human rights at Mass, isn't that using religious power for politics?”
The Church's answer: A priest has a duty to teach the Gospel and the Church's social doctrine on human dignity, life, peace, the poor, and justice. What he must not do is turn policy judgments — where legitimate disagreement exists — into the one correct answer of faith, or use the sacraments and the homily as campaign material for a particular candidate or party. Lay people have their own vocation: to form their consciences and to take part in concrete politics with their expertise and civic responsibility.
A further note — tell principles, policies, and candidates apart
Two people can agree on the moral principle “the poor must be protected” and still differ on which tax and welfare policy works best, because that turns on facts and technical judgment. A priest may name the Gospel's principles and obvious injustice, but among several legitimate solutions he may not make his own pick into God's command, or make support for a particular candidate a condition for the sacraments.
If they press further: “Should he stay neutral even in front of an unjust regime?” — When people's lives and rights are being crushed, silence may not be neutrality at all. A priest should speak clearly for the Gospel's principles and the voices of those being harmed rather than for partisan advantage, while checking the facts and not reaching for power himself.
In one sentence: “A priest has to speak the Gospel's social principles, but he must never use church authority and the sacraments as a propaganda tool for a candidate or a party.”
