1. Protestants believe that Purgatory is not supported by Scripture.

2. The liberal Protestants believe that Catholics are generally
saved. We conservative, non-fundamentalist Protestants believe that
there are still a remnant of true churches in the Catholic church,
and hence, some Catholics are indeed Christians. The fundamentalist
Protestant believe that Catholics are not saved at all.

Protestants believe both ways: that you can lose your salvation once
you are justified and that you can't lose your salvation once your
justified. Since I am Reformed Presbyterian, I believe that latter.

Martin Luther removed the Apocrypha (Tobit, 1 & 2 Macabees, etc.), a
chapter or two of Daniel, and a chapter or two of Esther because he
(along with the rest of us Protestants) believed that they were not
part of the original OT canon and thus were not divinely inspired
and infallible. Unfortunately, Luther went further than that. He
removed the inspired, infallible book of James from the body of the
Canon and put it into an appendix behind the end of the body. (His
removal of James flies in the face of Scripture where it talks about
not adding to or subtracting from the Bible.) This is one of the 2
reasons I believe Luther to be a heretic. (The other reason being
that he gradually slipped into heretically teaching salvation by

See my answer to #2. Liberal Protestants believe that the
differences in the doctrines of worship, authority, and salvation
are negligible. We conservative Protestants believe that those
differences in worship are important enough to remain separate from
the Catholic Church (in addition to liberal Protestant churches) and
for our Elders to not admit them to the Lord's Supper.
The 2 fundamental disagreements are how are saved and how the
authority of the Church relates to the authority of Scripture. Then
there are the disagreements on Purgatory and Indulgences, which date
back to 1517 (Luther's 95 Theses).
