Pope likely to alter economic message in the U.S., Vatican adviser says

Bishop Marcelo Sanchez Sorondo is chancellor of the Pontifical Academy of Sciences.

(CNN)Archbishop Marcelo Sanchez Sorondo has steered the Pontifical Academy of Sciences since 1998, but it's likely that his profile has never been more robustly public than now.

For the past year, Sanchez Sorondo has teamed with scientists and political leaders to help research, promote and defend Pope Francis' stern and sweeping condemnation of current environmental and economic trends.

    Some attendees, like California Gov. Jerry Brown, spoke very passionately about protecting the environment. Others, like many mayors in Italy, have more awareness of a new form of slavery, so it was important for them to be able to learn from each other.
    Q. It seems like the Vatican is partnering with quite a few people -- the Jewish feminist Naomi Klein, for example -- that would not be seen as traditional church allies. What is the strategy behind that?
    A: We understand that in this globalized world we all need to work together. As the Pope says in his encyclical, "Laudato Si," the Earth is our common home.
    And as we move towards setting new (United Nations') sustainable development goals, we also un
