It’s no secret that factions try to hijack Church teaching to either try to give their political platform credibility (if they are similar) or to discredit the Church (if they are opposed). For example, the Church teaching on caring for the poor is hijacked into either equating this teaching as a mandate to vote for a party platform or to indicate that the Church is being biased and therefore should not be heeded.
In America, both parties use both tactics, and some members of the faithful who want to promote a politcal cause will misquote Church teaching a way that makes it appear as if the Church is changing…either to praise the party or discredit the Church by accusing them of “becoming political.”
For people who get caught in it, this is nearly an airtight trap. It leads one to either think that fidelity to one political faction is fidelity to the Church, or to claim that they are being faithful to Our Lord or the earlier Church over the Church today.
