An unusual Midnight Mass: the real spirit of Christmas?

I like this poem very much. It is based on what may well be a myth, but to me it conveys the essence of Christmas:

Eddi's Service (A.D. 687) by Rudyard Kipling:

     Eddi, priest of St Wilfrid

      In the chapel at Manhood End,

     Ordered a midnight service

      For such as cared to attend.

     But the Saxons were keeping Christmas,

      And the night was stormy as well.

     Nobody came to service,

      Though Eddi rang the bell.

     'Wicked weather for walking,'

       Said Eddi of Manhood End.

     'But I must go on with the service

       For such as care to attend.'

     

     The altar candles were lighted,—

      An old marsh donkey came,

     Bold as a guest invited,

      And stared at the guttering flame.

    The storm beat on at the windows,

      The water splashed on the floor,

     And a wet yoke-weary bullock

      Pushed in through the open door.

     

    'How do I know what is greatest,

      How do I know what is least?

    That is My Father's business,'

      Said Eddi, Wilfrid's priest.

     'But, three are gathered together—

      Listen to me and attend.

     I bring good news, my brethren!'

      Said Eddi, of Manhood End.

     

    And he told the Ox of a manger

     And a stall in Bethlehem,

    And he spoke to the Ass of a Rider

     That rode to Jerusalem.

    They steamed and dripped in the chancel,

     They listened and never stirred,

    While, just as though they were Bishops,

     Eddi preached them The Word.

    Till the gale blew off on the marshes

      And the windows showed the day,

    And the Ox and the Ass together

     Wheeled and clattered away.

     And when the Saxons mocked him,

      Said Eddi of Manhood End,

     'I dare not shut His chapel

      On such as care to attend.'
