View of Church Doctrine as Monolithic is Erroneous – Pope Francis
“Let us get to specifics. Today it is a sin to possess atomic bombs; the death penalty is a sin. You cannot employ it, but it was not so before. As for slavery, some pontiffs before me tolerated it, but things are different today. So you change, you change, but with the criteria just mentioned. I like to use the “upward” image, that is, ut annis consolidetur, dilatetur tempore, sublimetur aetate. Always on this path, starting from the root with sap that flows up and up, and that is why change is necessary.
“Vincent of Lérins makes the comparison between human biological development and the transmission from one age to another of the depositum fidei, which grows and is consolidated with the passage of time. Here, our understanding of the human person changes with time, and our consciousness also deepens. The other sciences and their evolution also help the Church in this growth in understanding. The view of Church doctrine as monolithic is erroneous.
