“There is one among you whom you do not recognize.”
This is what St. John the Baptist said to the priests and Levites about Christ (John 1:26). The Son of God is here, but you are so obtuse, you don’t see it.
Even St. John himself had his moments of doubt about his cousin. When Herod imprisoned John, the Baptist sent his disciples to ask Jesus, “Are you the One who is to come, or should we look for another?”
The other St. John—the Evangelist—also pointed out that people did not recognize Christ. At the beginning of his gospel, St. John wrote: “Christ came to what was His own, but His own people did not accept Him.”
