If you divorce and remarry without benefit of church-sanctioned anullment then you are living in a state of adultery and are forbidden from receiving sacrements. Yet that is not enforced at the level of church hierarchy. And the quote from His Holiness that is at the top of this thread speaks of the sanctity of life from conception to natural death.
The prohibition on divorce is enforced, because divorced and remarried people are not allowed to receive the sacraments.
Usually the other quote is “innocent human life,” btw, because an exception has traditionally been made for justifiable killings of the guilty in war or through capital punishment.
But you’re not getting my central point, which is that divorce may be a violation of Church law and of God’s will for marriage, but it doesn’t deny the fundamental concept. Remember that Jesus introduced the prohibition on divorce as a new thing, since divorce was permitted and even abused by the Jews. Nowhere, however, has there ever existed the idea that two persons of the same sex may “marry.” Hence, this violates a premise of natural law, and it is not possible to build or run a just society on this basis.
Capital punishment is, again, a personal opinion; the words of the pope (or their translation) are not statements of doctrine, and until that happens, the Catholic doctrine on the matter remains unchanged. Various pro-abortion Catholics have attempted to add capital punishment to the life issues in order to dilute the attention paid to abortion and euthanasia and to make it sound like they’re all the same (the evil Bernardin “seamless garment” theory). They’re not.
