I know that Gaga is a believer and I am alright with that. The thing is that she doesn't try to cram her belief down anyone's throat. If asked she will respond but she doesn't bring it up herself.
Most religions postulate a deity who is perfect, such as Christianity. How can anyone look around this world and believe in a perfect god? Earthquakes, floods, tsunamis, fire storms, ice storms, droughts, volcanoes, plagues, hurricanes, tornadoes, famine and the occasional meteorite/ asteroid impact. AND apparently, even heaven isn't perfect or else why would some of the angels have rebelled against god? I just can't believe that the world we live on belongs on the resume of a "Perfect" being."
