Since there was a period of time between when Jesus lived and when the gospels were written, how can we trust that the writers' memories weren't faulty? And didn't they change history to match their theology? Actually, the "informed controlled": understanding of orality assures us that the writers were accurate and trustworthy. The gospels were not written right away because we prefer the testimony of eyewitnesses.
