So John said, ‘I am, as Isaiah prophesied: a voice that cries in the wilderness: Make a straight way for the Lord.’
Priests are sent to interrogate John the Baptist to try and identify his credentials. They are more concerned about him being a threat than they are about what it is he is saying. John allays their fears by denying he is the the Messiah or Elijah or the Prophet. He tells them he is simply a voice.
Saint John the Baptist, please pray for me.
