Nowhere in the any scripture does it say anything like that. It's just what YOU believe / claim. And I can guarantee you that the vast majority of actual followers of these religions, would disagree with you. Heavily.
Well then, tough tiddlywinks, because it does not MATTER what the followers of the religions think, it only matters what God thinks.

And it DOES say that in the scriptures of Baha’u’llah.
“But later Muhammad was “the Way” and now Baha’u’llah is “the Way.””
Uhu, uhu....
I guess that's why Islam is so fond and supportive of apostates, who leave islam exclusivity and why muslims love the Baha'i so much.
Like I just said, it does not MATTER what the followers of the religions think, it only matters what God thinks. God is always right because God is Infallible. The Muslims and previous religions simply did not get the latest message from God via Baha’u’llah so that are like a computer that needs UPDATES...
“No, the great religions do not contradict each other at all.”
You seem in denial.
Nope, I just know that an Infallible, All-Knowing and All-Wise God does not contradict Himself, so the ORIGINAL revelations that came from God are not contradictory, although theyare different, since the NEEDS of mankind have been different in every age.
A rough analogy is that you are a man and I am awoman so we are
different in certain ways, but that does not mean we have to contradict each other.
As I said before, what ends up happening is that humans change the original revelations from God by misinterpreting and mistranslating the original scriptures after which time the scriptures (and thus the religions) APPEAR contradictory.
“They all have the same spiritual teachings.”
They really, really, really, REALLY... don't.
Even within the denominations of a single religion, like christianity, there will be fundamental differences.... like "salvation through faith" vs "salvation through works" vs "salvation through faith + works".
Bzzzzzt...
First, you are talking about man-made dogma, so that is why there are fundamental differences that contradict each other.
Second, these doctrines are not the spiritual teachings of the religions; they are man-made doctrines, and since men think differently, the doctrines differ.
Now, let’s look at some actual scriptures of two different religions, Christianity and the Baha’i Faith, and compare the spiritual teachings. Then you will SEE how similar they actually are.
Matthew 7:24-27
Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock: And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock. And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand: And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it.
There is a very similar passage in the scriptures of the Bahai Faith:
“For every one of you his paramount duty is to choose for himself that on which no other may infringe and none usurp from him. Such a thing—and to this the Almighty is My witness—is the love of God, could ye but perceive it.
Build ye for yourselves such houses as the rain and floods can never destroy, which shall protect you from the changes and chances of this life. This is the instruction of Him Whom the world hath wronged and forsaken.”
Gleanings From the Writings of Bahá’u’lláh, p. 261
Here is another important spiritual teaching that is the same in Christianity and the Baha’i Faith:
Matthew 7:3-5
Why do you look at the speck in your brother’s eye, but fail to notice the beam in your own eye? How can you say to your brother, ‘Let me take the speck out of your eye,’ while there is still a beam in your own eye?You hypocrite! First take the beam out of your own eye, and then you will see clearly to remove the speck from your brother’s eye.
26: O SON OF BEING! How couldst thou forget thine own faults and busy thyself with the faults of others? Whoso doeth this is accursed of Me. The Hidden Words of Bahá’u’lláh, p. 10
Here is another important spiritual teaching that is the same in Christianity and the Baha’i Faith:
Matthew 16:24-26
Then said Jesus unto his disciples, If any man will come after me, let him deny himself, and take up his cross, and follow me.For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it. For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul?
“Thine eye is My trust, suffer not the dust of vain desires to becloud its luster. Thine ear is a sign of My bounty, let not the tumult of unseemly motives turn it away from My Word that encompasseth all creation. Thine heart is My treasury, allow not the treacherous hand of self to rob thee of the pearls which I have treasured therein. Thine hand is a symbol of My loving-kindness, hinder it not from holding fast unto My guarded and hidden Tablets….” Gleanings From the Writings of Bahá’u’lláh, p. 322
“It is established in all the prophetic cycles and it is renewed in every age
; religion teaches faith, knowledge, certitude, justice, piety, righteousness, trustworthiness, love of God, benevolence, purity, detachment, humility, meekness, patience and constancy. It shows mercy to the poor, defends the oppressed, gives to the wretched and uplifts the fallen......”
Good job ignoring reality once again.
You really do live in your utopian world of make-belief do you?
I just proved my point above. I am living in reality, and what I have are the ACTUAL scriptures to back me up. You are right that religions contradict each other, but THAT is because humans changed them. C’mon, I know you can figure this out, atheists are very smart. You just have to apply yourself and try to think
differently than you always have, given the NEW information I have presented.
Over here in actual reality, I see religion being divisive, poisonous, dishonest, corrupt, oppressive towards women, homophobic, unethical/immoral,...
Ignoring those aspects won't make them go away.
You are now in another ball park. AGAIN you are talking about what humans have done to change the original religions of God. So what you are talking about is what people do, not what the revelations from God actually teach.
You may start your excuses again now about how that is not religion but the people having false beliefs about it, while completely and utterly ignoring that all those things are right there in the scriptures - really not up for any "interpretation" whatsoever.
I will give you that there are some things in the Bible that are not what we should be following in this new day, such as oppression towards women and homosexuals, slavery, etc. That is one reason why we needed a NEW religion, humanity was sorely in need of an update.
“Religions build upon each other, like successive chapters in a book, each one leading up to the next.
They only appear to contradict each other because man has corrupted the true meaning of the scriptures over time, as noted above.”
And you have access to the "uncorrupted" originals or something? So who died and gave you all this secret information that apparently nobody else in the world has access too?
The problem is we do not have any original writings of any Prophets/Messengers of God that preceded Baha’u’llah so we only have what men wrote, men who were inspired by God... Then of course there have been transcription and translation errors so the Bible is even further removed from representing
the will of God. Yes, the Bible has been corrupted in certain instances and that is one reason why we needed a new revelation from God.
“It is the man-made doctrines and dogmas that contradict each other, but you cannot blame God for that, since humans have free will and they mess things up every chance they get.”
Typical apologist....
"Everything I don't like, I'll blame on humans. And everything I like, I'll attribute to God".
That is because I am logical. An Infallible God cannot make any mistakes, only fallible humans can make mistakes.
Typical atheist....
"
Everything I don't like, I'll blame on God or religion. And everything I like, I'll attribute to humans who don’t believe in them".
