John, generally thought to be the last of the four canonical gospels, is the only Gospel that potentially dates to 80 years after Jesus's death.
Per TFA The synoptic gospels are thought to have been completed no later than 95 CE, with historical dates for the crucifixion (for those that consider the crucifixion factual) 30-33CE, placing them as no more than 65 years after the crucifixion.
