Buddha is the Luther (reformer) of Hinduism. Both trashed the institutional body of their religions (the Vedas & casts in Buddha; the Church in Luther) to get a more spiritual faith.
Religions can be positioned in a scale from: A. the merely spiritual (no rites, no priests, all is interior) like New Age and Liberal Protestantism, to Z. the purely material, like Paganism or China’s Confucianism (no interiority needed).
Catholicism, because of the its interpretation of the Incarnation of God, is, in this scale, closer to Paganism than to Protestantism.
Do you think religions should be purely spiritual?
