A logical fallacy to demand historical evidence of a historical assertion?

That’s not how this works my friend. You don’t get to invent your own history because you don’t like the sources we have. If you don’t like what Eusebius, or Irenaeus, or anyone else wrote, then show me how and where they were wrong.

And competent historians know how to pull out the opposition’s arguments from the Catholic sources. When Origen wrote “Against Celsus”, he cited many of Celsus’s arguments. Augustine’s works are full of Manichean beliefs that he refuted.

A logical fallacy to demand historical evidence of a historical assertion?

It's a logical fallacy to appeal to authority. Not too mention a red herring and a straw man.

I don't need a historical source to give authority to an already well established timeline of historical events.

The time frame of the book of Revelation as written by John is known. The time of Linus and Clement are also known. I don't need a historical source to over lap the two.

Nor am I obligated to find a Catholic source proclaiming the Catholic Church being apostate. Unless you count Martin Luther...

I can however, look at documented historical events involving the Catholic church and evaluate those events as compared to the teachings of Jesus Christ on my own. Such events like the Spanish Armada, which was an attempt by the Catholic Church to win back England from the protestants by way of war. This event is not in dispute. And completely contrary to the commandments of God as given by Jesus Christ Himself.

I look at the writings of Paul, where he explicitly says that in the last days there would be false churches teaching the doctrines of the devil. Paul saw this in vision and stated that a sign would be that they forbid to marry. Being these are the last days, the very time Paul saw in vision, which of all the churches have any laws forbidding marriage? The Catholic church forbids every member of it's leadership from marrying. There's no one else Paul could have seen in that vision. That certainly doesn't describe my Church.
