“For in the things that are crucial and essential, they speak with one voice. Therefore, if they did not diverge in the essential points, why do you marvel if they appear to vary in minor details? It is precisely because they did not agree in every detail that we can see that they present the truth. For if they had agreed in every point it would cause the suspicion that they had sat down and deliberated together to write the Gospels. Instead, what one evangelist has omitted, another has written down, and it is for this reason that they seem to be at variance on some points.”

(St Theophylact,  on the content of the four Gospels)
