So no one has any control over the Bishops? I am not a Catholic so why would a Catholic Bishop listen to anything I have to say? I bet if the Pope publicly denounced the Catholic politicians that openly support abortion by name people would take note.
Sadly, most Protestant churches reference abortion little as well.
It would be satisfying, even fun, to see a nice, noisy censer come down on the head of these scandalous public and political figures, whose full time hobby horse is to be seen and heard parading as a Catholic, so they can appear to be a reliable authority in bashing and distorting the beliefs of the Church.
These people have long ago excommunicated themselves from the Catholic Church, which means they are no longer in communion with the Church.
ExCatholics are just that, until which time they admit their scandal, their sin against the Church, their grave error, repent and do penance that is as public, to the same degree as their error.
Just because you aren’t Catholic doesn’t mean you can’t write some letters to tickle their consciences. A protestant calling them their apparent hypocrisy on the matter of pro-abort politicians might be the the last straw, as it were. Public excommunication is a legitimate use of their teaching authority to keep others from falling into the sins of abortion.
I would suggest keeping it to abortion where their is a clear church position that they are not upholding and keeping any peculiarities of where you disagree with Church teaching to yourself. If you try to make any doctrinal points that disagree with the Church your point on abortion will be lost.
