Vatican City – Pope Benedict XVI on Thursday defended the Vatican’s right to speak out on bioethics, including its opposition to artificial procreation methods and embryonic stem cell research, and dismissed criticism that the Church blocks scientific progress.
“Church teaching certainly cannot and must not weigh in on every novelty of science, but it has the task to reiterate the great values which are on the line and to propose to faithful and all men of good will ethical-moral principles and direction for new, important questions,” Benedict said.

Benedict brushed off those who have criticized the Church, “as if it were an obstacle to science and to humanity’s true progress.”
The pope singled out as “new problems” the freezing of embryos, selecting which embryos should be implanted after testing them for defects, research on embryonic stem cells and attempts at human cloning. He decried them as proof that “the barrier protecting human dignity has been broken.”
Benedict was addressing a meeting of the Congregation for the Doctrine of the Faith, a powerful Vatican office which safeguards doctrinal orthodoxy. Before being elected pope in 2005, he headed that office.
