 Cardinal Karol Wojtyla of Poland. He was heavily involved as a council father at Vatican II. And this section of Gaudium et Spes is so crucial and it just pops up again and again and again in the writings of JP II, how we have to make our lives a gift to others, just like Jesus made his life a gift for us on the cross. And when we see this, that's when we look at the cross and the Sorrowful Mysteries are centered on the cross.
