There are notable exceptions. For instance, there is a movement Marx probably never dreamed possible in organized religion, entitled Liberation Theology. It rose out of South American and Latin American freedom struggles, struggles against US colonialism. The teachings of Liberation Theology resemble the teachings of Christ. In them the rare synthesis of religion and spirituality is realized.
Spirituality is part of the essence of humanity.
It is what gives human beings hope, what helps us through troubled times. Organized religion is devoid of spirituality when it becomes dogmatic. We can religiously go to our church, synagogue, or mosque each sabbath, but it is only when we look beyond ourselves and care for others that we have taken the first step towards spirituality.
