The four canonical gospels are not the only ones. Recent research and archeology have uncovered gospels attributed to Thomas, Mary, Judas and others. These gospels, found in 1945 at Nag Hamadi in Egypt, suggest that in the early centuries a great competition (and conflict?) raged between what we now know as Christianity and an earlier and quite different form: gnostic Christianity. These matters were fully discussed with us in 2007 by two great biblical scholars, Bart Ehrman and Elaine Pagels.
