It's been a long time. Also, I'm sure there are many people watching the thread who weren't around for that. So a repeat of these criteria would be nice.
Please bear in mind that the following criteria are
my criteria which is based upon who I believe were Messengers of God, who met all these criteria. My criteria narrow the playing field and it will eliminate most claimants, since they will fail to meet all the criteria.
The minimum criteria would be:
1. He had good character as exemplified by his qualities such as love, mercy, kindness, truth, justice, benevolence, gracious, merciful, righteous, forgiving, patient.
2. He believed he had been given a mission by God and did everything he could to see that it was carried out. He was completely successful before his death, and he accomplished everything that he set out to do.
3. He wrote much about God and God's purpose for humans both individually and collectively, or scriptures were written by others who spoke for him. He firmly believed that the work he was doing was for the Cause of God.
4. He had many followers while he was alive, and there are still millions who follow his teachings and gather in groups based on the religion he founded.
5. His followers have grown more numerous in recent times.
This is a starting point but there are other questions we would want to ask ourselves before we would be able to believe that a man was a true Messenger of God because that is a bold claim so there should be a lot of evidence to support such a claim.
So just more empty claims. Vague claims of "miracles", but nothing more.
They are not just claims, but miracles are not proof to anybody except those who witnessed the miracle.
Famous Miracles in the Baha’i Faith
"Bahá’u’lláh forbade His followers to attribute miracles to Him because this would have amounted to the degradation of His exalted station. Nevertheless, there are many accounts left to posterity by His disciples, describing the circumstances in which He either healed incurables or raised the dead.
None of these supernatural acts were considered by His followers to be a proof of the truth of His Cause, since they are only convincing to a limited number of people and they are not decisive proofs even for those who see them."
