Nice try but we all have access to the supposed writings of Ignatius and his word was 'catholic', not, Catholic...To turn catholic into a specific denomination as your religion has done is nothing less than deceitfull...
Koine (New Testament Greek) did not use Capital letters, or punctuation for that matter.
Let us put aside what Ignatius meant by “Catholic”. If you put what he believed side by side to what Catholics and Protestants believe today he would be Catholic. This is true of the other early Church Fathers who are witnesses of what the early Christians believed.
There was no capitalization at all in the 2 Century. If you read the letter, you will know that St. Ignatius calls Catholics to obey their bishop and stay away from heretics that don't recognize the Body and Blood of Jesus in the Holy Eucharist. (Proof).
