Evangelii Praecones §56

⁵⁶ Another end remains to be achieved; and We desire that all should fully understand it. The Church from the beginning down to our own time has always followed this wise practice: let not the Gospel on being introduced into any new land destroy or extinguish whatever its people possess that is naturally good, just or beautiful. For the Church, when she calls people to a higher culture and a better way of life, under the inspiration of the Christian religion, does not act like one who recklessly cuts down and uproots a thriving forest. No, she grafts a good scion upon the wild stock that it may bear a crop of more delicious fruit.
