His mother, Mary.

The Blessed Virgin Mary. She believed that her son, Jesus, was her Lord and Savior even while he was still in the womb. With love in Christ.

Jesus did NOT come to establish Christianity. He was a Jewish prophet who saw the priests making a mockery of the religion. By their practices they had killed off the spirit of the Law, so that the real purpose of the Law, the reforms it was meant to achieve was lost. They had over the years become experts in weaving their way around the letter of the Law, in identifying loopholes in the wording and exploiting those loopholes. Thus they could allow what was unlawful and forbid what was lawful, and in each case they made sure that no one could argue that they had broken the Law as it was worded. They prided themselves in not having violated the letter of the Law, not caring that in the process they had thoroughly ruined the spirit of the Law. Jesus was incensed by what the priests had done calling them hypocrites. He wanted to launch a revolution to change all that. To give pride of place back to the spirit of the Law, so that it could do its intended work of changing individuals and society for the better. The priests launched a campaign against Jesus and, according to the Bible, had him eliminated. Even without Jesus the movement continued to operate from the synagogues. However, without a clear leader it began to lose focus. A Jew called Saul had been a chief persecutor of the reformed Jews. He oversaw, and perhaps even participated in the killing of St. Steven. Saul claimed he saw Jesus in a vision which changed him from being a persecutor of the movement to their champion. Paul realized that the movement would remain a small minority if recruitment was restricted to Jews only. So he relaxed the Law and opened up recruitment to all gentiles. Followers of the movement were first labeled Christians, by their persecutors, around the year 45. With the above in mind perhaps it could be argued that the first Christian was Paul.

They were first called Christians in The city of Antioch as mentioned in the book of Acts. Christian means Christlike. So it would seem to me Jesus would be the First Christlike.

Probably either John the Baptist or the disciples, most would probably say. But, actually, the Old Testament saints were technically Christians because they followed God and beleived that He would send the Messiah(Jesus Christ) in the future, so they were Christians(followers of Christ) since Christ was God. So, really, it is hard to say for sure. I hope that this helps. :) -In the Master's service. Thank you and God bless you!

The various prophets that predicted His first coming, His mother, Mary, or the three wise men that found Him in the manger shortly after His birth, take your pick ... but the first use of the term "Christian" was back in about 70 to 80 years after His birth, in about 45 AD , as mentioned by "borasalama"

Nietzsche said there was only one Christian and he died on the cross.

Armenian's and thats that!!!

The first person to have that personal relationship with our lord Jesus and knew all that he taught while accepting what he must do to save us and restore our prefall relationship with God , was none other than a woman. She was a princess in the line of David and Jesus preformed his first miracle for her even though it was not yet time. Let it be done unto me according thy will O God. He was flesh of her flesh and if we love her son like she does then we can surely call ourselves Christian

Judas, because he sold out Jesus, thus founding the behavioral realities of Christianity which exist to this day.

I was going to say Jesus, but I saw someone else said Blessed Virgin Mary, and that makes good sense to me, so I'll go along with that answer.
