Religare = ' to establish the bond again'.
We are all religious as the human being is transcendent, always looking to what is behind or further from the mere matter or metaphysical; (meta (after,beyond) - physical (matter, accessible via our 5 senses ).
Spirituality is the state of being reached when you transcend the matter, even if a little bit.
In short religion and spirituality are the goal, the finish line of evolution, thus not in conflict.
RE: Is spirituality and religion supporting the evolution of humanity to move forward , or is spirituality and religion holding us back?
