According to available information, the situation is this:
In Brazil, a nine year old girl is sexually abused by her step-father (note: he hasn't been convicted, so I hereby make the obligatory genuflection towards Our Lady of the Presumption of Innocence) and becomes pregnant (with twins!). When her mother finds out, she seeks an abortion for her daughter, which the medical system is willing to grant, given both the rape and the fact that she's still too young to safely carry even one child to term, let alone twins (thus managing to hit not one, but two exceptions to Brazil's general ban on abortion).
And the Catholic Church, displaying the matchless Love of Jesus, tried to prevent it.
Fortunately for this poor kid, her doctors went ahead and did the abortion anyway.
So the local Archbishop excommunicated them. And the girl's mother. There's no word on whether the anathema also applies to the evil bastard who's responsible for the whole mess in the first place.
BTW, the Brazilian Catholic Church seems to be on a roll these days: just last week, they suspended a priest from his duties, for his advocacay of gay rights, and the use of condoms as a public health measure.
But back to the excommunications: the girl is off the hook, as she's too young to be held accountable. However, I can't help thinking that as she grows up, she will remember what her Church did for her in the darkest hour of her young life, and react appropriately. As for her mother and the medical personnel: I also can't help thinking they're better off being on the outside of this insane institution.
