I think the real disconnect between Christianity and Hinduism-Buddhism is regarding who the human being is, in relation to God. For Christians, human beings and God are two distinct kinds of persons, whereas for Hindus-Buddhists, they are the same at source.
I got one of my Hindu friends to send me relevant extracts from their holy book, The Gita. Here Krishna, an avatar of their Supreme God, is speaking to his charioteer Arjuna. Krishna says: *"Many births have been left behind by Me and by thee, O Arjuna, I know them all, but thou knowest not thine, O Parantapa.
This eternal individual Jiva (= human being), the world of Jivas, is a ray of Myself and at the time of leaving the body he draws round himself the various senses, that is, the sense of hearing, sense of sight, sense of touch, sense of smell and sense of taste, with the mind as sixth sense, all these having their abode in Prakriti i.e., the world of matter, as distinguished from the Purusha, who is the Paramatman. When He acquires a body, and when He departs from the same, the Isvara takes these and goes out, even as the wind is laden with fragrance gathered from flowers and other sources. Verily, the perverted and the deluded do not perceive Him, who thus leaves the body, or who resided and enjoyed in the body in conjunction with the senses; but the Sages, endowed with the eye of wisdom, do perceive Him.
There are two classes of beings in the world, the perishable and the imperishable. The perishable comprises the whole of Creation, together with the Universe of changing forms, whereas the imperishable is the eternal and the immutable. Different even from these two is yet the highest spirit known as the Paramatman or the Supreme Self, the immutable, who penetrates and nourishes the three worlds. Insofar as I transcend the perishable and the imperishable and because I am superior to them, I am realised as the Purushottama or the highest divinity in the world of Seers and Scriptures."*
In identifying the human person as “a ray of Myself”, Krishna clearly implies that man, at source, is co-eternal with God, and therefore just like Him, has no beginning. By contrast, in Christianity, before conception: void. At the instant of conception, poof!: individual/person. Also in Christianity, a man, once created, remains a distinct person eternally, whereas in Hinduism he/she, at the point of moksha, surrenders his individual ego, and in doing so, gets merged back into the Supreme Self or Para Brahman. So in Hinduism, man, in essence, is divine. The disconnect between the two faiths begins from here and flows into everything else, such as resurrection v/s reincarnation. And this being a doctrinal matter, there can be no arbitration as to where the truth lies, though it has to lie in either of the camps and not in both. As a Christian, if I claim to be uncreated/without a beginning, I commit blasphemy, since that is claiming equality with God. As a Hindu-Buddhist, if I say that I am distinct from God (i.e. I hold on to my ego), I commit heresy and by definition deny myself moksha. It’s a very clear-cut dilemma and no amount of argument or dialogue can resolve it. It is better that we appreciate what divides us, and co-exist amicably, without deriding the other (Christians please note) and without trying to subsume the other (Hindus-Buddhists please note)
