Vatican City, Oct 11, 2015 / 10:02 am (CNA/EWTN News).- Archbishop Charles Chaput of Philadelphia spoke to the synod fathers on Saturday on the importance of precision in language, particularly regarding unity in diversity, and recalled the Protestant Reformation.

“Imprecise language leads to confused thinking,” the archbishop said Oct. 10 at the Vatican, giving “two examples that should cause us some concern”: 'inclusive' and 'unity in diversity'.
