I agree that morals are taught by example or words reinforced by example. When the example contradicts the verbal lesson (hypocrisy), the example IS the lesson, not the words.
This is a good aspect of education to agree upon. There is too much hypocrisy in education.
This is my objection to Christianity calling itself a religion of love because it has a scripture that says love another, yet doesn't do that itself by humanist standards of love, which wouldn't include blood sacrifice, crucifixion, damnation, or hell. There'd be no apple dangling before children to see if they can resist (Spoiler: they can't) then punishing them for being human. There also would be no global flood, a gratuitously cruel attack on all terrestrial life plant or animal.
Personally, I see if one is a Christian they are also a humanitarian , a lover of all humanity, and most importantly look after the world we live in by maintaining a balance in our material pursuits.
That is why God renews religions and promises never to leave us without guidance. As humans we tend to turn unto our material animal nature, and forgo our spiritual potential.
The Christian was also given law that must be followed if the balance is to be found, Islam is the same. If we neglect the laws, or change them to suit our animal calling, then the balance is lost.
Apart from the homophobic doctrine, I don't know enough about what the Baha'i believe to critique it analogously. Do they accept original sin, damnation, and hell theology? Do they even believe in an afterlife? A paradise? If so, who goes where and according to what rules? The Christian versions of justice (eternal hell for not believing an unevidenced claim?) and mercy (there are no appeals for the damned) are just as deformed as the example given of love.
I am not good at answering so many points, I find it difficult to focus. At school I would tackle a problem, get it finished, but never did the final tidy up one may say! The reports would always say, need to pay attention to detail.
So the multi questions. "Do Baha'is accept original sin, damnation, and hell theology?"
No to original sin doctrine. We have been told we are created on the edge of darkness and the beginning of light. That means that our animal nature is the darkness and our spiritual capacity is the light. Our purpose, in this matrix (womb of our spiritual birth and growth) is to find and cultivate our spiritual capacities. So heaven and hell are states of being, hell is lack of spiritual capacity, heaven is obtaining to our spiritual capacity, (Nearness and Remoteness from God is heaven and hell). This is why Jesus said we must be born again from the flesh into the Spirit. Death cannot overtake this birth. (Big topic)
Do they even believe in an afterlife? A paradise?
As mentioned above, when born from the flesh into the Spirit, there is no death, as it becomes an eternal consciousness. Paradise is nearness to God, hell is remoteness. This topic is also immense and requires a lot of study and meditation on what is offered.
I can offer what I understand. If one does not embrace the Spirit, it is like a rock in this world, it exists, but without consciousness, this is a state of being we see as hell, remoteness from God. Embracing the spirit allows that consciousness to fly like an eagle in all the world's of God. Have you ever had those dreams where you fly, or can runs so fast it defies logic?
If so, who goes where and according to what rules?
Every Soul passes on to the Spiritual Worlds under the bounty and mercy of God. A just God that fulfills all that was promised and all that was warned against. They pass to that world in the spiritual state that they obtained in this life. If the chance was not given, then this is under the bounty of God.
The rules are simple, the Messengers of God give those rules and guidance. Our spiritual limbs are grown on submission to those laws and guidance.
So it is quite possible that a person who has not hear of the Messenger, but lives their life according to those rules and guidance, is more a Baha'i than someone who claims to be.
This is a big topic and as to the form we take in the Spiritual worlds, much is written but little explained, as it is offered there is no comparison or words that can be offered to such a joyous state of being.
(You may be aware many NDE accounts offer that the experience is un-describable) this is also a good talk by Abdul'baha.
