Which Holy Book did Abraham write? Even with Moses there's a good chance he wrote nothing. If not these "manifestations", then who did write the Bible and the other Jewish Scriptures? Then there is the NT... even with the gospels we are uncertain who wrote them. Yet, you trust that Jesus really said and did what the gospels say? No. As we all know, Baha'is only believe some of the things written.
You do remember that God sent a flood to kill everybody. He sent fire and brimstone to destroy a couple of cities. And that he ordered the Israelites to kill all the men, women and children in Jericho.
The Aztecs and other people have had religions where they sacrifice humans. Even religions mentioned in the Bible are called evil and false. Some religions of some people were just no good.
Yes, it's the Baha'i way that includes the Baha'i interpretation of what is true about the other religions.
Thanks CG for asking these questions and I’m sorry i cant always give you the best answer. I’m still learning and researching on all these questions you bring up and try as much as possible to avoid personal opinion but to just find for you what the Manifestation said so you are best informed.
When it comes to ancient religions, many records have been lost and so we Baha’is rely upon what the current Manifestation has stated. Abraham is recognised as a Manifestation .
Abraham
“He established the oneness of God, for at that time the generality of mankind were idol worshippers.” (SAQ) I am unaware of any Book of Abraham. The Bible has many Books with many attributed authors and also some Books with ‘unknown’ authors.
The Torah of Moses
the Torah that God hath confirmed consists of the exact words that streamed forth at the bidding of God from the tongue of Him Who conversed with Him (Moses).
(Baha’u’llah)
Know ye that the Torah is that which was revealed in the Tablets unto Moses, may peace be upon Him, and in that which He was commanded to do.... The glorious Book, the Mighty Decree, is what was in the Tablets which Moses, upon Him be peace, brought from Mount Sinai, and that which He proclaimed unto the Children of Israel, in accordance with the explicit text of those Tablets. (Abdul-Baha)
Know ye that the Torah is that which was revealed in the Tablets to Moses, may peace be upon Him, or that to which He was bidden. But the stories are historical narratives and were written after Moses, may peace be upon Him. (Abdul-Baha)
The Gospels
The Four Gospels were written after Him [Christ]. John, Luke, Mark and Matthew - these four wrote after Christ what they remembered of His utterances. (Baha’u’llah)
The Bible
THIS book is the Holy Book of God, of celestial Inspiration. It is the Bible of Salvation, the Noble Gospel. It is the mystery of the Kingdom and its light. It is the Divine Bounty, the sign of the guidance of God. 'Abdu'l-Bahá
Some of the stories like the flood, Adam and Eve, have been explained as not real occurrences but to teach us some lesson. Book of Certitude, SAQ)
Yes there are some religions which are man made that may be evil and human sacrifice is likely one of them.
