Lazarus

Birth
Lazarus was born as the younger brother of Saint Martha. His parents fell sick and died at a young age, leaving him to be raised by his sisters. His parents death left him with an obsession with living forever.

Life
Lazarus lived his life as an alchemist, attempting to find a potion for eternal life. He did thousands of experiments and accidentally killed dozens of people with his potions, but got closer and closer.

Jesus
When Lazarus heard Jesus, renowned as a bringer of life, was coming to his town, he was very excited. However, upon meeting, Jesus sensed great potential in him as an alchemist, and being afraid and jealous, as if Lazarus was successful, he would no longer be the only immortal. Due to this, Jesus attempted to have him assassinated, but it was already too late, and Lazarus survived with his immortality.

Lazarus confronted Jesus in private, and the two immortal men fought, with Lazarus's serum allowing him to instantly recover from any attack Jesus could use. Eventually Lazarus got the upper hand, and was able to land a single, solid punch on Jesus, the first time any mortal was able to strike a god as such. Out of Jesus's fear, several angels descended upon Earth and destroyed Lazarus, but he had undoubtedly disturbed the prophecy forever by forcing Jesus's exposure to heaven again, therefore weakening the end result to an extent where a second coming would be nearly impossible.

Aftermath
Lazarus's family declared war on the church forever, resulting in such events as the tale of Saint Martha of Tarascon.

The presence of angels also disturbed the Christian prophecy, making another manifestation incredibly difficult for Jesus.
