the author(s) of the Didache (written sometime between AD 50 and AD 110)
Ignatius of Antioch (ca. AD 35 - AD 110) early bishop of Antioch, was taught by St. John)
Since these people wrote things that do not line up with scripture and are contrary to scripture, why would you assume they are NOT the people the apostle Paul was referring to???
2Co 2:17 For we are not as many, which corrupt the word of God: but as of sincerity, but as of God, in the sight of God speak we in Christ.
Act 20:29 For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.
Act 20:30 Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them.
Anything that is contrary to --- that is, strictly ruled out by ---Scripture, is not part of Apostolic Tradition.
So even if you found something in, say, the Didache, which was strictly ruled out by Scripture (and I don't think you can, but I'm open to you trying) --- that erroneous item you found, would not be a part of Apostolic Tradition.
And those supposed "church fathers" certainly have their disciples here on FR.
