“Your definition of “Apostasy” is hypertechnical”
It’s the correct definition. Apostasy refers to doctrine not the conduct of the members.
“One can Apostatize by continued sin”
One can personally apostasize through sin, yes, but has already been explained, the Church cannot.
“The Catholic Church through the Counter Reformation implicitly recognized its organizational sin and reformed.”
Yes and the organizational sin was not a doctrinal apostasy. They reaffirmed what had always been taught and went forwards. This is contrary to the protestants who committed doctrinal sins and apostasised.
“It is a great question whether or not God recognized its reformation.”
Alright, let me ask you a question.
If I were to prove to you that every protestant church does not teach today what they once taught previously, would you believe that protestants have apostasised?
