What happened in those few minutes he describes as the final conclave votes were counted was that the Pope's heart was moved by the suggestion of a friend to choose a name that represents exactly what the world needs most right now: peace, solidarity with the poor, and care for the environment.
This is not some retro-hippie flower-child leftist vision, but, in the end, is the agenda of Catholic social teaching. It represents not only the spirituality of Saint Francis, but the very teachings of God himself.
excellent summary from the Archdiocese of Chicago or the Catechism of the Catholic Church 2302-2317 on "Safeguarding Peace"
USCCB document on solidarity with the poor and the Catechism of the Catholic Church 2443-2449 on "Love for the Poor" for more background.) This becomes even more important in a consumer society where some are left out, as our new Pope has already demonstrated by his own actions and frequent mention of the poor.
Each creature possesses its own particular goodness and perfection. For each one of the works of the "six days" it is said: "And God saw that it was good." By the very nature of creation, material being is endowed with its own stability, truth and excellence, its own order and laws. Each of the various creatures, willed in its own being, reflects in its own way a ray of God's infinite wisdom and goodness. Man must therefore respect the particular goodness of every creature, to avoid any disordered use of things which would be in contempt of the Creator and would bring disastrous consequences for human beings and their environment. (339)and even more pointedly, this:
The seventh commandment enjoins respect for the integrity of creation. Animals, like plants and inanimate beings, are by nature destined for the common good of past, present, and future humanity. (2415)Pope Francis will not be the first to preach the message of peace and respect for creation. Pope John Paul II's 1990 World Day of Peace statement, "Peace with God the Creator, Peace with All of Creation" noted that the ecological crisis is a moral crisis.
These then, are the apparent priorities of the man who has just stepped into the papal office at the call of the Holy Spirit to serve the Church in this time. He has discerned the world and heard its pain. He dedicates himself with a father's love to help people of faith work together to do what they can to transform that pain into promise. Long may he serve!
