Judges 13:2-7, 24-25a; Ps 71(70):3-4a. 5-6b. 16-17; Luke 1:5-25
The story of Samson's conception is strikingly similar to that of Jesus with his mother, Mary. The child born however was very different! Although Samson did make a huge progress towards the salvation of his people, particularly against the Philistines, he did it in a a very human way. He defeated them, taunted them, in a way similar to how some recent politicians do in the modern world. Samson was a man of power and strength (and again, like many modern politicians, he had a weakness ready to be exploited).
Not at all like Jesus.
Note also other differences between the conceptions: There is no 'fiat', the Yes of Mary that was the moment the world changed forever. There was no apparent acceptance of the immaculate conception - it could almost be a tale told by an errant wife! The angel was in no way differential to the woman - quite the opposite indeed.
And no glorious leap of joy, no 'Magnificat'.
