One of the pope’s titles is “Pontifex Maximus” or “Supreme Pontiff.” Pontiff means bridge builders. Pope Francis says that Christians must build bridges, not walls.
Here is what Pope Francis wrote in his encyclical (letter) called Laudato Si: “At the end, we will find ourselves face to face with the infinite beauty of God and be able to read with admiration and happiness the mystery of the universe. Even now we are journeying towards our common home in heaven. Eternal life will be a shared experience of awe, in which each creature, resplendently transfigured, will take its rightful place and have something to give those poor men and women who will have been liberated once and for all."
In heaven, we will find ourselves face to face with the infinite beauty of God, as Peter, James & John were when they saw Christ transfigured (glorified) on the mountain. We are all on this journey toward common home in heaven & that eternal life will be a “shared experience of awe.” In other words, while walls may be necessary on earth, there will be no walls in heaven. Francis said that each creature will be transfigured. Even our bodies will be glorified. So now, we are in the process of being changed, transfigured, transformed. Christ is our Bridge from sin to grace, hatred to love, from this life to the next.
