These are just words. As you use to get something said, catch what you suspect, and be reasonably understood by others, it’s a wobbly dance. (Like the one who painted with jam in buttermilk on television many years ago?) 🙂
Anyway, spirituality I let be the overriding concept, the phenomenon. Spirituality is newer spirituality, new age and with it. Religion, yes the institutionalized, the reasonably enduring and slowly changing, in both tradition, conception and matter.
