How very welcoming of you.
There are so many reasons why Luther broke off from Catholicism, pretty much all of them applicable yet today.
Until the Catholic church reforms, there will be a large schism.
See post #8. This is all about one theological truth.
The schism between the Eastern Orthodox and Roman Catholicism happened five centuries BEFORE the Reformation and that rift has not been mended. Like you said, until or unless the Roman Catholic church reforms those dogmas that caused those splits, the schisms will remain. People may come and go, but the problem is with Rome.
Luther was vindicated in part by the counter-reformation, but the fact is that today much of American Lutheranism bears little resemblance even to that of twenty years ago.
