Does anyone know the religion denomination of David Petraeus and Paula Broadwell?

I tried a routine search and could only find that Petraeus attended the Presbyterian church as a child.

I do not assume this is true.

I did not find anything on Broadwell.

I am doing a research paper on religion and values that contribute to setting the "community standard" or the lack of a community standard in my community as it relates to public behavior that affects public policy as it directly relates to what the press media in my community calls the upper and lower tier in the community. In other words studying what appears to be a double standard one for insiders and elites and one for the rest of us. Example locally we had a man freed from 25 years of prison because he was found innocent 2011-2012 using evidence available at the1987 trial time frame that was not allowed by the upper tier in Williamson county Texas. In the 1998 [probably years before] 2011-2012 REVELATION (this is a biblical term) of the Penn State University leadership dynamic leadership dynamic there had to be more than one person guilty if the one person convicted had the run of the lubrication oil and the locker room. [As an aside I always ask my self when a male on male abuse/use scandal occurs in a public dynamic - why do we rarely hear of the other combinations specifically male on younger female and older female on female and male?] What religion dynamic and oversight function [especially religions that make marriage a sacrament] and what values and principles dynamic allows disparate [knowledge and values that are easily delineated in COMPETENT and THOROUGH per-martital counseling]couples to even marry in the first place? If Petraeus and Broadwell are America's best what type ethics and morals does the middle and the worst have? Is there a disconnect somewhere along the continuum? I do not know for sure but is it possible the lower levels of eliteness have better values and ethics? To become an elite at the public level do you have to commit a wrong to get there? If honest and decent is taught it is wrong to do wrong does that make them dicriminated against when it comes to advancing to eliteness?
