I honestly don’t think most Prostestants would have any idea what any of those groups were.
I had never heard of any of them until I began investigating the Catholic Church. If you had said Arianism to me, I would have assumed that you were talking about the Aryans, the Master Race of Madame Blavatsky and eventually Hitler.
Of course, probably most of the Protestants on this Board are much more knowledgeable than I was.
As I began studying Catholicism, I recognized much of my evangelical Protestant teaching in gnosticism. Evangelicals tend to diminish the body/flesh/matter and elevate the spirit/soul. Many times I have been admonished to “Forget the body and concentrate entirely on Jesus.” In other words, there was something “wrong” or “unclean” about my hunger, my thirst, my sleepiness, my pain, or my need to use the bathroom.
For much of the 1970s, there were a lot of evangelical teachings out urging Christians to “deny” their body. I specifically remember being taught that we don’t need to sleep more than a few hours out of the 24, and that we should rise early in the morning, around 3 A.M, to pray and study the Bible before our school or work.
This is rank gnosticism, a denial that we are human flesh, and that this flesh was created by God with a need for sleep. I remember feeling so guilty that I was unable to go without sleep. Thankfully wiser Protestants came along in the 1980s and urged us to respect our bodies rather than abuse them.
Another manifestation of Protestant “gnosticism” is the failure to accept that earthly things can be used for spiritual purposes, e.g., the waters of baptism. To a Protestant, all of these earthly things are just “symbols,” because things of this earth have no value. Flesh is not of God, only our spirits are of God.
Anyway, I think if you were to post this same poll on a primarily Protestant website, most people would react by saying, “Say what?” (And then, of course, you and your post would be kicked off the Protestant Board along with all the other Catholic “non-Christians!”)
