Somethings remain the same

As heresy after heresy is listed, I felt the following comment by Irenaeus had some contemporary parallel:

"These men, even as the Gentiles, have been sent forth by Satan to bring dishonour upon the Church, so that, in one way or another, men hearing the things which they speak, and imagining that we all are such as they, may turn away their ears from the preaching of the truth; or, again, seeing the things they practise, may speak evil of us all"

Or even the following:
"Many offshoots of numerous heresies have already been formed from those heretics we have described. This arises from the fact that numbers of them — indeed, we may say all — desire themselves to be teachers, and to break off from the particular heresy in which they have been involved. "
