Can a missionary that is licensed to the gospel ministry still claim the exemption (see below)

I am a full time missionary for a missions organization. I get paid monthly by organization and they are offering to give me a housing allowance.

My questions are:
1. I am licensed to the gospel ministry, but not ordained. Can I still claim the allowance?

2. Even though I get paid by more organization, they send me a 1099 at the end of the year, which I think makes me "self-employed" by the IRS. Does this make a difference?
