Your flesh and blood are nourished by eating Jesus flesh??? I can understand that...Your church fathers were African...There's a history of folks in Africa who get/got their nourishment from eating flesh...Just sayin'...
Since one set of Ignatius' writings mention nothing 'Catholic', we can assume you are quoting the known forged writings that were attributed to Ignatius???
Stop using anti-Catholic websites as your sources and actually go to a university library. There are 15 extant letters allegedly authored by St. Ignatius. the seven epistles of Ignatius of Antioch were forged in the 3rd or 4th centuries. The other 8 are genuine. (note: The fact that some would seek to have forgeries associated with St. Ignatius only reinforced the value of his legitimate letters.) The term Catholic was used in The Epistle to the Smyrneans, one of the eight legitimate letters.
The term was also used by other second century authors in the Martyrdom of Polycarp, written in c. 155 AD, and in the Muratorian fragment written in c. 177 AD.
Peace be with you
