Pope Francis said:

"Things have a price and are saleable, but persons have a dignity, they are worth more than things and they have no price. Because of this, attention to human life in its totality has become in recent times a real and proper priority of the Magisterium of the Church, particularly for life which is largely defenseless, namely, that of the disabled, the sick, the unborn, children, the elderly."

and

"Every unborn child, condemned unjustly to being aborted, has the face of the Lord, who before being born, and then when he was just born, experienced the rejection of the world. And every elderly person, even if he/she is sick or at the end of his/her days, bears in him/herself the face of Christ. They cannot be discarded!"

(Pope Francis, Vatican City, Sept 20th 2013)
