[Theophilus]

Apostasy has always been as near as the nearest and dearest pagan traditions and (little "o") orthodoxy and (little "c") catholicity has always been as near as the Canon. Christianity has never entered into apostasy but we have always had apostates among us. Many so-called: "Protestants" are chock full of apostasies. It is not enough to deny the authority of Rome you must also assert the authority of scripture.

[Destro]

May I ask historically what strain preserved non Apostate Christianity that appeared in Northern Europe about 200-300 years ago?

I would love--as a historian-to be able to track its progression from the Greek East up the North of Europe and then to North America.
