"a well-formed Christian conscience does not permit one to vote for a political program or an individual law which contradicts the fundamental contents of faith and morals. [...] This is the case with laws concerning abortion and euthanasia (not to be confused with the decision to forgo extraordinary treatments, which is morally legitimate). Such laws must defend the basic right to life from conception to natural death." - Doctrinal Note on Some Questions Regarding the Participation of Catholics in Political Life

Doctrinal Note on Some Questions Regarding the Participation of Catholics in Political Life

Is this an offical "Ex Cathedra" statment of the church? If so, I would appreciate a source link.

I am curious because I investigated the question of Catholics being told how to vote. I concluded that there no official statements about it, but that there were plenty of radicals giving their opinon as if it were Ex Cathedra.
