In Paul’s day, to be circumcised was the visible sign for Jewish men of their faith; they were indelibly marked, changed as a symbol of their faith. For centuries circumcision, or not, was a raging controversy for Christians. Today, for many Christians the visible sign is wearing a cross that can be taken on or off, even used as a fashion accessory. Holy Baptism leaves no visible, long-lasting mark. Think about those who visibly show their faith, their love of God, their devotion to their beliefs—how do you know he or she is a person of faith? How would anyone know you were a person of faith?
