Martin Luther and his followers left the Church, and started up a new one. The Church itself did not split.
An alternative explanation would be that Martin Luther was kicked out of the church (unjustly when he only wanted to reform the church from evil practices) and then anathematized.
You might consider this explanation as spin, but I don’t see why it is any more spin than yours.
A neutral and unbiased reader of reformation might be able to cut through the spin jobs on both sides and figure out that the truth of the matter is a little more nuanced than the spin doctors on both sides would lead him to believe.
Someone who is unbiased would not start with the assumption that any one side is more at fault than the other and would be skeptical of anything he thinks as spin.
Have you read Numbers 16, yet?
Several times as a matter of fact.
As I recall it ended with a pretty swift judgement of folks getting swallowed up alive into the earth.
What gives me (and should give an impartial observer) pause here, is that I see nothing indicative of God’s judgement upon Protestants. In fact if I must say so, I see some evidence of his blessing (now to be fair I see some evidence of his blessing upon Catholicism too).
This would be in contrast to heresies(arianism,gnosticism…) where they are pretty much discredited (you might argue they rear their ugly heads from time to time…but they
are discredited amongst orthodox Christians…and we don’t see a first gnostic church or a second arian church around do we).
In fact your own pope (JP) doesn’t even believe we are heretics and the equivalent to Korah. If he did, he never would have said to Billy Graham “We are brothers”. He would be treating us as Iranaeus treated the heretics of his day (read Iranaeus and see how he viewed heresy…none of this separated brethren schmuck).
If its good enough for your pope, its good enough for me.
