As forerunner of our Lord’s birth, preaching and death, the blessed John showed in his struggle a goodness worthy of the sight of heaven. In the words of Scripture: Though in the sight of men he suffered torments, his hope is full of immortality. We justly commemorate the day of his birth with a joyful celebration, a day which he himself made festive for us through his suffering and which he adorned with the crimson splendour of his own blood. We do rightly revere his memory with joyful hearts, for he stamped with the seal of martyrdom the testimony which he delivered on behalf of our Lord.
-- Saint Bede the Venerable from a homily on the martyrdom of Saint John the Baptist
