Every single time you present a passage from the Bible and say the passage is correct because it bolsters your faith, but other passages which do not bolster your faith you dismiss as corrupted alterations made by man.
In short, you determine whether a passage is valid or not by whether it helps you out or not.
As far as "organized" religions go, and religions that claim to be from an all-knowing and all-loving God, the Baha'i Faith isn't too bad. And I'm sure the world would be better off following some of their precepts. But... what's troubling is that they do exactly what your saying they do. Here's the beginning of Acts chapter 1...
1 In my former book, Theophilus, I wrote about all that Jesus began to do and to teach 2 until the day he was taken up to heaven, after giving instructions through the Holy Spirit to the apostles he had chosen. 3 After his suffering, he presented himself to them and gave many convincing proofs that he was alive. He appeared to them over a period of forty days and spoke about the kingdom of God. 4 On one occasion, while he was eating with them, he gave them this command: “Do not leave Jerusalem, but wait for the gift my Father promised, which you have heard me speak about. 5 For John baptized with water, but in a few days you will be baptized with the Holy Spirit.”
6 Then they gathered around him and asked him, “Lord, are you at this time going to restore the kingdom to Israel?”
7 He said to them: “It is not for you to know the times or dates the Father has set by his own authority. 8 But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.”
9 After he said this, he was taken up before their very eyes, and a cloud hid him from their sight.
10 They were looking intently up into the sky as he was going, when suddenly two men dressed in white stood beside them. 11 “Men of Galilee,” they said, “why do you stand here looking into the sky? This same Jesus, who has been taken from you into heaven, will come back in the same way you have seen him go into heaven.”
This creates several problems for Baha'is. So are these verses allegorical, man-made, false additions? Did the early Church misinterpret them? Baha'is can use any of these to make these verses say or mean whatever the Baha'is want them to mean... or to be totally false. Since who wrote this stuff anyway? Some guy named Luke? Was he even an eyewitness?
Anyway, in verse one it says Jesus showed himself alive. Baha'is say that Jesus never came back to life. He's dead and stayed dead. The resurrection verses are allegorical. Here's
Abdul Baha's interpretation...
Therefore, we say that the meaning of Christ’s resurrection is as follows: the disciples were troubled and agitated after the martyrdom of Christ. The Reality of Christ, which signifies His teachings, His bounties, His perfections and His spiritual power, was hidden and concealed for two or three days after His martyrdom, and was not resplendent and manifest. No, rather it was lost, for the believers were few in number and were troubled and agitated. The Cause of Christ was like a lifeless body; and when after three days the disciples became assured and steadfast, and began to serve the Cause of Christ, and resolved to spread the divine teachings, putting His counsels into practice, and arising to serve Him, the Reality of Christ became resplendent and His bounty appeared; His religion found life; His teachings and His admonitions became evident and visible. In other words, the Cause of Christ was like a lifeless body until the life and the bounty of the Holy Spirit surrounded it.
Then it talks about the baptism of the Holy Spirit. This sets up what comes up later at Pentecost. The disciples get filled with the Holy Spirit. For Christians this is the fulfillment of the coming of the "Comforter" But, for the Baha'is, that's not what any of this means. When Jesus said that a Comforter was coming, Baha'is say that he was referring to the coming of Baha'u'llah 2000 years later.
Then another thing Baha'is make allegorical, Jesus is taken up into the sky. But, it also says this "same" Jesus will come back. This and any other verse that makes it sound like Jesus will return, for the Baha'is, is wrong. They interpret it in a way that satisfies them. And, for them, that's all they need, because their guy, Baha'u'llah, and their religion, The Baha'i Faith, can't be wrong. Therefore, it's all the other religions that are wrong. But, they say, the non-existent "original" teachings of all the messengers all taught the truth about God. It was the followers of the religion that screwed it all up and brought in false teachings and beliefs that contradict the things the Baha'i Faith teaches. And who knows, maybe so. But it sure makes God look like an idiot to have sent so many messengers that didn't write down the message themselves but let others write it and get it wrong. And then let others add in and misinterpret those writings.
So, for me, even though Baha'is say they believe in all the other religions... there isn't really that much that they believe about any of them. Of course except for a few bits and pieces.
