The execution would occur a week after Pope Francis revealed new church teaching that deems the death penalty “inadmissible” under all circumstances.

“The huge thing,” she said, is the recognition by the church of “the inviolable dignity even of guilty people who have done terrible crimes.”

Pope Francis' revision of the Catechism of the Catholic Church to assert that capital punishment is morally inadmissible shows how the church can grow in its understanding of the implications of basic tenets of faith.

Pope Francis has revised the church’s catechism to state that the death penalty is no longer admissible.

Sister Helen Prejean, an anti-death penalty activist and author of the book Dead Man Walking, joins Kevin Clarke to discuss Pope Francis' revision of the death penalty teaching.

The revised teaching declares that the death penalty is an attack on the inviolability and dignity of the person, and that the church works "for its abolition worldwide."
