|St. Ignatius and the Lions Icon|
St. Ignatius dubbed the Church the Catholic Church a millennia before the split of the Church. To claim that the Catholic Church made up her name in the 11th century is, as I stated before, to be ignorant of history. The mutual split between the East and the West in the 11th century has only deepened over the centuries. We need to be talking and communicating more on our similarities and commonalities rather than purposely pushing each other away.
"The two forms of the great tradition of the Church, the Eastern and the Western, the two forms of culture, complement each other like the two "lungs" of a single body." —Pope John Paul II, Euntes in mundum, 1988. http://www.catholicculture.org/culture/library/view.cfm?recnum=3700
One final thought: "We have not only to be called Christians, but to be Christians." -St. Ignatius of Antioch
