Neither. If you are thinking of this in the concept of a Abraham's religion (Christianity, Islam, or Judaism), in which a prophet or messiah is a spokesman or embodiment of God.
For Buddhist, The Buddha was an enlightened person who fully understood the world and how we are to live in it, in peace, harmony and without suffering. He is our teacher and mentor.
Hindus have adopted The Buddha as as avatar of Vishnu; that is, an embodiment of Vishnu, akin to how Jesus was the embodiment of the God of Abraham.
Buddha never claimed to be a God or taught of a God. He was asked by a follower before His death; if there is God and why He didn't teach of a God. He said 'I taught you, how not to suffer. So why do you need a God? If you learn my teachings, then you can become your own God'. He taught you that your God is within you. So therefore, all you need is Nirvana and perfect Dhamma. He saw man and women suffering over a God in his younger days. So He taught you, not to worry over these things. Because it will lead to a long road. He took for many years, before coming into enlightenment. When He was younger, He would ask to why there was suffering, death and hunger. It is said that He went to almost every Brahman to learn their teachings. He would ask them all as to why there was hunger, suffering and death. All said that is a part a life. So He wanted to teach man and woman, no matter who you are, no matter, rich or poor, not to suffer. Since women could not learn from Brahmans during his time.
The Messiah is probably as important as Moses the Prophet is.
No. A prophet predicts the coming of the messiah. Christianity sees Jesus as the messiah, the one whose coming was predicted.
The prophet Isaiah told the Israelites about the coming Messiah
Elijah or Elisha
All Christians believe that he was the Messiah and St. John the Baptist was the last prophet.
prophet, priest, king
Jesus is the Messiah and was Muslim as he called to full surrender (Islam in Arabic) to God; the Creator. However, if you mean the prophet of Islam per Quran God revelation, then he is prophet Muhammad.
Christianity: Son of God (Messiah) Islam: Prophet Judaism: False messiah
Jewish people believe that Jesus was a prophet, not the Messiah, and not the Son of God. They believe that the Messiah is still to come.
No prophet had an impact in His ministry. Rather, the opposite was true. Isaiah prophesied the most about the Messiah to come.
The prophet of the Most High and Precursor (forerunner) of the Messiah.
Siddhartha is the historic founder of Buddhism. Mohammed is the historic prophet of Islam. There is no confusion between the two anywhere in the world by people with any knowledge of religion or philosophical teachings.
