 The same meaning is attributed also to "Roman Catholic" in older documents of the Holy See, talks by Popes and in newspapers.Although K. D. Whitehead has claimed that "the term "Roman Catholic" is not used by the Church herself" and that "the proper name of the Church, then, is 'the Catholic Church', never 'the Christian Church'," official documents such as "Divini Illius Magistri", "Humani generis", a declaration of 23 November 2006 and another of 30 November 2006, while not calling the Church "the Christian Church", do use "Roman Catholic" to speak of it as a whole without distinguishing one part from the rest.But ecclesiologists normally seen to be as diverse as Joseph Ratzinger and Walter Kasper agree that one should never use the term "Roman Catholic" to denote the entire Catholic Church.
