Specifically, St. John the Baptist. With whom we share a ministry to be prophets:
As for you, little child, you shall be called a prophet of God the Most High.
You shall go ahead of the Lord to prepare his ways before him;
to make known to his people their salvation
through forgiveness of all their sins;
the loving-kindess of the heart of our God
who will visit us like the dawn from on high.
He will give light to those in darkness,
those who dwell in the shadow of death,
and guide us into the way of peace!
(from Luke 1:68-79)
