Jesus, who redeemed humanity by giving up his life on the cross, shows that it is not strength that saves the world, but the "weakness" of boundless love, the papal preacher told thousands of people gathered for the Liturgy of the Lord's Passion at the Vatican.

While he did not celebrate Mass or wash the feet of inmates, Pope Francis made his customary Holy Thursday visit to a detention facility, arriving at Rome's Regina Coeli jail at about 3 p.m. April 17.

Priests are called to continual conversion so that they can authentically preach the good news of hope, Pope Francis wrote in the homily he prepared for the Holy Thursday chrism Mass.
