From the BBC Online:
Cardinal Barragan told the newspaper: "Soon the Vatican will issue a document about the use of condoms by persons who have grave diseases, starting with Aids."
He said his department was studying the document, along with the scientists and theologians who wrote it.
"It is Benedict XVI who asked us for a study on this particular aspect of using a condom by those afflicted with Aids, and by those with infectious diseases," he added.
Asked whether he agreed with Cardinal Martini's views, Cardinal Barragan said: "It is a very difficult and delicate subject which warrants prudence."
He said he preferred not to comment on Cardinal Martini's remarks, so as "to not anticipate the study".
It is not clear when the document will be published.
The Vatican has made no official comment.
Further info on the "nuns in the Congo" referred to in my comments above:
Father Gonzalo Miranda, who lectures at the Pontifical Academy of the Regina Apostolorum, and is Secretary of the Institute of Bioethics at Rome's Catholic University, said that the use of the Pill is sanctioned in such cases if the women ran "a serious and imminent risk of rape".
In an interview published by the Italian Bishops' Conference official news agency, SIR, which lends his views extra weight, the theologian said: "Contraception is morally illicit when it accompanies a desired sexual act, but when a sexual act is imposed, and not wanted, then contraception represents the only form of protection."
He added: "In such cases the act of taking the Pill . . . is not a true act of contraception from the moral point of view, but only an act of defence."
The question of nuns taking the Pill as a defence in trouble spots around the world was openly authorised long ago in the case of the Congo by Cardinal Pietro Palazzini - even if the Pope's authorisation of the prelate himself was never publicised.
