Why do Christians (and Monotheists) have such a problem with those that worship pluralistically?
Such as Paganism and Hinduism?
Three reasons:
- Christians are bound by the commandment "Thou shalt not have other/strange gods before me". Nowhere does the Bible deny the existence of other gods. The usage of "false gods" is incorrect.
- Christians are further bound by Jesus's comment "I am the way the truth and the life. No one comes to the Father but through me". But this is completely misinterpreted.
- Christians are bound by the Great Commission, Jesus's order to his disciples to go make disciples of all nations.
Therefore, any religion or belief system that doesn't adhere to these three requirements is evil and false as they see it. Hindus see the nature of God as being completely unlike the Abrahamic concept. Brahman, usually popularly and not-entirely-correctly referred to as "God" manifests in uncountable ways, forms and names. In my personal beliefs, Brahman manifests even as Thor, Zeus, Xango, Yemaya, Perun, Taranis, Odin, Frigga, and every "pagan" or Pagan god/dess. I can go off-trail into why the Aztec gods are so bloodthirsty ... same reason Yahweh and Allah (or any god) are viewed as being, petty, bloodthirsty and vengeful: misunderstanding and misinterpretation.
"Whatever deity a devotee seeks to worship with faith, I steady the faith of such a devotee in that form." BG 7.21
" ... even those devotees who faithfully worship other gods also worship Me. But they do so by the wrong method." BG 9.23
So, Sri Krishna sanctions worship of other gods as long as they understand what proper worship is and is not. But this is repugnant to Christians and cannot be sanctioned.
