‘Spirituality’ is not something owned by any one Church or religion. It is how we journey through life in relation to those things which are of ultimate importance to ourselves. These might be a personal sense of integrity, a code of ethics, a deep personal commitment to the other human and sentient life around us.
For Christians it can be all of these things but each one finds their meaning and purpose in God. For the Christian, the spiritual journey is one of relating to this God, who is the ultimate cause and meaning behind everything that is.
