Roosters?

With Easter approaching, the CCD classes are having some in depth discussions. This past week, they were discussing Peter betraying Jesus 3 times before the rooster crowed. These are the questions that came rapid fire from the backseat the other day on the way home from class...

Margaret: How did Jesus know Peter was going to betray him?

E.J. : What does 'betray' mean?

Charlie: They had roosters back then???
