From my perspective, I consider all religions as man made. We have been inventing them from the beginning of time. However I do believe in God.
So to me, photographing man- made structure like churches, or whatever your religion calls them, is meaningless. It is only honoring the people that made them.
If you do believe in God, one would probably conclude that he/she made this earth and by photographing the beauties of this planet you are indeed, honoring God.
That being said, if you wish to see the perfect manifestation of God, look into the face of a child.
Of course of your intent is to photograph the nuances of different religions or their customs, then that is another matter.
