Jesus did mention that the 10 could be boiled down to 2  .
He also gave us the 8 Beatitudes  .  Not that much attention is paid to them !  
Seeing how little we truly loved ourselves he added  "  love one another as I have loved  you  !
Why we forget Paul's lengthy discourse on the powerlessness of the 10 commandments to do anything but convict us of sin   ( letter to the Romans ).   is beyond me  .
