Spirituality, philosophy and religion as not the same. Add one particular word to all three and that becomes evident. Extremism, which is defined as the quality or state of being extreme, advocacy of extreme political measures, radicalism. (WebsterÂ’s 9th new collegiate dictionary)
If you have a Spiritual extremist it is not likely that they will cause much if any problem, a philosophical extremist, possibly. But a religious extremist is a whole different breed of cat. Religious extremists have been responsible for the Crusades, cults and much of the international terrorism of today.
Also Philosophies can become religions, examples of this are Taoism and Confucianism.
And the definitions of these three words is not exactly the same if you are taking Eastern Philosophy not Western.
But since, I am assuming, we are all Westerners, and in this discussion, since you are comparing Spirituality, philosophy and religion I am assuming that you are referring to Religious philosophy. If that is the case there is no difference between the 2. But Philosophy is not religious philosophy. Religious philosophy is a part of philosophy much the same a historical philosophy and scientific philosophy.
Philosophy, Spirituality and Religion are defined as follows in the Dictionary of Philosophy and religion, Eastern and Western Thought.

Philosophy begins in wonder, tells us that this discipline is concerned with the investigation of the cause and principles of things. But within this there is first philosophy or theology.

Philosophy is the elucidation of ultimate truth whose starting point is found by pushing skepticism to its limits. At that limit the certainty of ones own existence is revealed.
