Pope Francis is denouncing how new technologies are making it easier for people to change gender, saying this “utopia of the neutral” risks the creation of new life.

Francis made the comments Thursday to the Pontifical Academy for Life, the Vatican’s bioethics advisory board, taking up his criticism of so-called gender theory and the idea that people can choose their sex.

But Francis kept to the church’s hard line against gender theory in his first meeting with the new members Thursday.
