Once the angels departed, the shepherds said to one another: Let us go over to Bethlehem and see this thing that has happened for us (cf. Lk 2:15). The shepherds went with haste to Bethlehem, the Evangelist tells us (cf. 2:16). A holy curiosity impelled them to see this child in a manger, who the angel had said was the Saviour, Christ the Lord. The great joy of which the angel spoke had touched their hearts and given them wings.
Let us go over to Bethlehem, says the Church’s liturgy to us today. Trans-eamus is what the Latin Bible says: let us go “across”, daring to step beyond, to make the “transition” by which we step outside our habits of thought and habits of life, across the purely material world into the real one, across to the God who in his turn has come across to us. Let us ask the Lord to grant that we may overcome our limits, our world, to help us to encounter him, especially at the moment when he places himself into our hands and into our heart in the Holy Eucharist.
