In Mark 12:30-31, Jesus says:
'One of the teachers of the law came and heard them debating. Noticing that Jesus had given them a good answer, he asked him, 鈥淥f all the commandments, which is the most important?鈥
鈥淭he most important one,鈥 answered Jesus, 鈥渋s this: 鈥楬ear, O Israel: The Lord our God, the Lord is one. Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.鈥 The second is this: 鈥Love your neighbour as yourself.鈥 There is no commandment greater than these.鈥'
