The problem is that you're looking at it from a Christian perspective.
No, I'm explicitly not looking at it from a Christian perspective. If I did, I'd call all non-Christian spirituality either fake or demonic. I gave a secular description of spirituality that maps onto Buddhism and Christianity alike.
Buddhism is very clear about it. Spirituality is about training one's mind and state of being in order to reach peace among people.
"We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ."
-2 Corinthians 10:5
"Rejoice in the Lord always; again I will say, rejoice. Let your reasonableness be known to everyone. The Lord is at hand; do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus. Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is an excellence, if there is anything worthy of praise, think about these things. What you have learned and received and heard and seen in me -- practice these things, and the peace of God will be with you."
-Philippians 4:4-9
"For this is the message you heard from the beginning: we should love one another...Do not be surprised, my brothers and sisters, if the world hates you. We know that we have passed from death to life, because we love each other. Anyone who does not love remains in death. Anyone who hates a brother or sister is a murderer, and you know that no murderer has eternal life residing in him. This is how we know what love is: Jesus Christ laid down his life for us. And we ought to lay down our lives for our brothers and sisters."
-1 John 3:11-16
This is the main argument of this thread. Buddhism has everything we need to progress because in order to progress we need at least not to kill one another.
Given that the Christian West voluntarily stopped killing people in the name of religion around the 18th, 19th, and 20th centuries without these values being imposed on them by an outside force, why do you think this is unique to Buddhism? And do you think violent Buddhist fundamentalists aren't a thing?
