As far as I know, neither Luther nor "the Pope" (which Pope? Certainly not the present Pope, nor his immediate predecessor) "embraced" heliocentrism.
I'm sorry, Virginia-American, but I am really not following you here. Help???
The RCC officially adopted heliocentrism in 1822. (link to catholiceducation.org).
Luther's (and other early Protestants') condemnation of Heliocentrism is well known - discussed here
