A few snips from the statement, with my emphasis added in bold:
Some interpretations have presented the words of the Pope as a contradiction of the traditional moral teaching of the Church. This hypothesis has been welcomed by some as a positive change and lamented by others as a cause of concern – as if his statements represented a break with the doctrine concerning contraception and with the Church’s stance in the fight against AIDS. In reality, the words of the Pope – which specifically concern a gravely disordered type of human behaviour, namely prostitution (cf. Light of the World, pp. 117-119) – do not signify a change in Catholic moral teaching or in the pastoral practice of the Church.
As is clear from an attentive reading of the pages in question, the Holy Father was talking neither about conjugal morality nor about the moral norm concerning contraception. This norm belongs to the tradition of the Church and was summarized succinctly by Pope Paul VI in paragraph 14 of his Encyclical Letter Humanae vitae, when he wrote that "also to be excluded is any action which either before, at the moment of, or after sexual intercourse, is specifically intended to prevent procreation—whether as an end or as a means." The idea that anyone could deduce from the words of Benedict XVI that it is somehow legitimate, in certain situations, to use condoms to avoid an unwanted pregnancy is completely arbitrary and is in no way justified either by his words or in his thought. On this issue the Pope proposes instead – and also calls the pastors of the Church to propose more often and more effectively (cf. Light of the World, p. 147) – humanly and ethically acceptable ways of behaving which respect the inseparable connection between the unitive and procreative meaning of every conjugal act, through the possible use of natural family planning in view of responsible procreation.
