“Christ expressed all His teachings in His last commandment: ‘Love each other, as I loved you. Everyone will see that you are my disciples, if you love each other.’ He did not say, ‘If you believe,’ but ‘If you love.’ Faith can change with time, because our knowledge is constantly changing. Love, on the contrary, never changes; love is eternal.”

Leo Tolstoy, A Calendar of Wisdom (Page 20)
