Untrue—but Nevertheless True!

Regarding the effort to determine which of the historical Jesus' sayings are authentic or inauthentic: 

It has been said of Winston Churchill that half the things attributed to him are untrue—but are nevertheless true! On the same principle, should we not abandon altogether the attempt to shuffle the Gospel sayings and pericopes into two piles, labelled ‘authentic’ and ‘inauthentic’? Does not any attempt to do so inevitably distort the truth? It would seem that those who have pursued the ipsissimi verba Jesu in the belief that this would take them to the historical Jesus have in fact succeeded only at shunting themselves into a siding.
