It seems to me the issue is not about doing something to "get you into heaven". The issue seems to be that as a person who believes you are saved, what do you do with your faith; what does God call you to do; ignore the poor in your community, or simply lend a helping hand with others? If your are saved, is your contribution "polluted" if it is co-mingled with contributions from the "unsaved", who had the same good intentions, good expression of their faith, as you did?
If you do not stand and present yourself, with your faith, openly, among people who have not come witness your faith, then who will? The only door you are closing is the door you shut your faith behind.
"It seems to me the issue is not about doing something to "get you into heaven". The issue seems to be that as a person who believes you are saved, what do you do with your faith; "
And that, I believe, is the message in the passage from James that I quoted. It is not that works will get you into heaven, according to Christianity, but that works are evidence of your faith.
I suspect that the second chapter of James is not one of the frequently used texts in the church which cancelled its donation. It's not a popular New Testament book among some Protestant denominations.
God knows what you do and why you do it.
In the end, that's all that matters.
