[one Lord one faith one baptism]

Killen’s thesis for the supposed forgeries can be summed up with “they can’t be truly written by Ignatius because the contents prove the Catholic Faith and we know that Faith is false”.
Unfortunately for Killen, whtever “controversy” that existed in the 19th century has long since been settled as all honest scholars admit the seven epistles were indeed written by Ignatius. James White, a rabid Anti-Catholic, equal to Killen in his opposition to the Catholic Faith, even admits the epistles were written by Ignatius.
but why do some still cling to the long disproved forgery allegation?
the reason is obvious. everyone i hope will agree St John understood the Eucharist. now i think everyone will agree that if SR, verga, iscool and i spent just a few weeks listening to St John preach on the Euchrist, all four of us would be able to faithfully to write a letter explaining the doctrine of the Eucharist, just as we learned it from St John. sooooo, if St Ignatius indeed wrote that the gnostics abstained from the Eucharist because they did not believe it was the flesh of our Savior Jesus Christ, you can see the problem those that oppose the Catholic Faith have. They would have to believe St Ignatius misunderstood St John, even though St Ignatius was so well thought of in his faithfullness to Christ and His Church that he was made bishop of Antioch and later proved his love for the Lord by dying a martyr’s death. add in the fact that what Ignatius wrote garnered no opposition from anyone concerning his doctrine and the cry of “forgery” is all the opponents have.

It is well know that there are two sets of what amounts to be the same 7 letters...One set has no reference to Catholicism...The other set is full of things Catholic...Ignatius is credited by the Catholic religion as to being the father of the movement...

If any of the letters have any authenticity, which group would an unbiased person lean towards???

Regardless, it has been researched by boatloads of people and it is pretty common for Catholic to deny the accusations and evidence...There are some Catholic researchers however who have agreed that there are forgeries...

Ignatius as well as many others wrote against the Gnostics because Gnostics rejected the truth that Jesus even HAD a physical body that suffered and died. When one reads the writings of these people back then one should be aware that the arguments WRT the flesh of the Savior related to THAT heresy and not the much later developed one of the Eucharist being trans-mutated into the literal body and blood of Christ.

Also, "Killen's thesis" notwithstanding, it is NOT true that "all honest scholars" accept the Ignatian letters as genuine. Among those scholars who have questioned their authenticity - with good reasons - include Philip Schaff (in his book "Ante-Nicene Fathers" and "History of the Christian Church") and Henry C. Sheldon ("History of the Christian Church").

The explanations for why some and even all of the presumed epistles of Ignatius may be spurious can be seen HERE.

And, let us not leave out the very critical point that gets missed frequently...the early church "fathers" did not speak infallibly, they were not divinely inspired when they wrote their letters and, if what they wrote contradicts Holy Scripture, it is Scripture which holds preeminence.
