Heh.
As I noted on another thread, I consider the "the Episcopalian Church was once noble and godly, but now they've lost their way" talking point to be on par with the "Democrats used to be honorable and patriotic and the conservative party in America until they changed" argument.
There were (and STILL are, though difficult to find) decent Christian and God-fearing members of that church, as well as clergy, but the Episcopalian church OVERALL has been rotten since Day One.
George Washington being an Episcopalian is similar to Bob Casey Sr. being a Democrat. So what?
I don’t think Trump was endorsing the Episcopal sect.
He went there because it is an historical site, IMO.
