As a Baha'i I believe in an invisible essence called God and that Krishna, Moses, Buddha, Christ and Muhammad are all Manifestations of God. In that sense there's no division and we are all one people, with One God, following one religion. That is my believe but it is not the belief of those who I converse on this thread. That's fine. We're all entitled to our beliefs as you are.
The Abrahamic and Dharmic Faiths do represent two lineages if you like.
Buddha as you know emerged out of Hindu India and then His Teachings spread throughout Asia.
Christianity emerged from Judaism. 600 years later Muhammad encouraged his peoples to turn away from paganism to follow monotheism in the traditions of Moses and Jesus and announced the Qur'an was the next revelation from God surpassing the gospels and Torah.
My RF associates here will argue that the Abrahamic and Dharmic Faiths have such different paradigms as to be irreconcilable. I don't believe that a all of course. Nor do you.
You (again) used the expression "Dharmic faith". I explained that
Dharma had nothing to do with any faith, it is a universal concept, not something associated with a "faith" or a particular local culture. So to speak of a Dharmic faith makes no sense at all to me.
Even speaking of Abrahamic faiths is debatable because the essence of Christianity does not seem to really build on Judaism but rather on Hellenistic ways of thinking.
So I don't see that there are 'two lineages' and the separation seems to me artificial (perhaps only useful for the sake of classification on Wikipedia).
This whole idea of making such an artificial separation probably stems from the idea that so-called
monotheism is an important or even essential criterium for classifying traditions. Jesus himself speaks of the Abba (beloved Father), the Holy Spirit (Supreme Consciousness) or Rule of God (Self-realisation) which seems philosophically/cosmically more in line with a tantric-mystic outlook than anything to do with Judaism.
It is unlikely that Buddha the person ever thought of himself as "emerging out of Hindu India". He was just trying to find a better way of following and teaching Dharma as so many other teachers in Asia had tried before him (and after him). Buddhism was once popular inside South Asia as just another way of following the Dharma. Of course the pandits disliked Buddhist hinduism because buddhists had no need for their paid ritualistic services and defied their caste system (although buddhists in South Asia probably ended up in their own caste).
So there is no need to "reconcile" imaginary lineages, it is in my opinion much better to abandon such divisive thinking altogether and look at the underlying basic spiritual or mystic teachings that really matter to spiritual life and ignore the more superficial differences over which religious people like to quarrel.
