Please do not attempt to use secular and vernacular sources to dispute the definitions and meanings the Catholic Church uses in describing itself and it's doctrines and dogmas. When we very narrowly define a word for use in communicating it is done with the expressed purpose of NOT using allowing the secular world to define us and what we believe. You have no idea how irritating and dismaying it can be to make a very specific statement about what we as a Church or we as individuals mean and have non-Catholics and poorly catechised Catholics reply with "no you don't".
