Who am I to say there is any deficiency, incompleteness or error? I am lower than the dust that Christ walked upon.
It is God that sends the Messengers, it is God that corrects our misunderstandings and errors in the given Message
If I pass that God given Message on, then surely that is a given bounty, not an error. Jesus said one must pickup the Cross to follow him, that obviously means that on the path of acceptance, many who are in error, who will not accept the new message, they will see that as a wrong choice.
Supercessionism is but doctrine, what does God say?
Example is the Sermon of the Mountain
Mathew chapters 5 to 7
We can consider who were the blessed when they were charged with spreading the Message.
Why is there a Blessed people? Was it those that chose to be Christians (those that accepted Christ) blessed at this time and not the Jews?
Jesus gave us the key “Do not think that I have come to abolish the law or the prophets. I have come not to abolish but to fulfill".
So what would one expect from a Baha'i, knowing they see Baha'u'llah offered He is the One Jesus Christ and all the Prophets have Promised? After all it was openly declared to
POPE PIUS IX.
If one reads that linked Tablet, does that not impart a Message? That message was not mine to give, but only to share.
It's not an error that I share it, as I am only passing on that Baha'u'llah did not come not to abolish, but to fulfill.
It is only seen as an error if one chooses not to believe the truth that Tablet contains, which is logically your stance.
So it is not personal attacks on any people of any faith Thomas and never will be. God is the judge and we are all judged by the "Word of God".
This is an extract from the end of the quoted Tablet
"... Verily, the day of ingathering is come, and all things have been separated from each other. He hath stored away that which He chose in the vessels of justice, and cast into fire that which befitteth it. Thus hath it been decreed by your Lord, the Mighty, the Loving, in this promised Day. He, verily, ordaineth what He pleaseth. There is none other God save He, the Almighty, the All-Compelling."
