Gospel
Matthew 1:18-23
‘That which is conceived in her is from the Holy Spirit.’

Now the birth of Jesus Christ took place in this way. When his mother Mary had been betrothed to Joseph, before they came together she was found to be with child from the Holy Spirit. And her husband Joseph, being a just man and unwilling to put her to shame, resolved to send her away quietly. But as he considered these things, behold, an angel of the Lord appeared to him in a dream, saying, ‘Joseph, son of David, do not fear to take Mary as your wife, for that which is conceived in her is from the Holy Spirit. She will bear a son, and you shall call his name Jesus, for he will save his people from their sins.’
All this took place to fulfil what the Lord had spoken by the prophet:

‘Behold, the virgin shall conceive and bear a son,
and they shall call his name Emmanuel’ —
which means, God with us.
