It could not be that they were not who seemed now dead, but by glorious martyrdom they were advanced to eternal life; and consolation is for those who have suffered loss, not for those who have reaped a gain. Rachel affords a type of the Church long barren now at length fruitful. She is heard weeping for her children, not because she mourned them dead, but because they were slaughtered by those whom she would have retained as her first-born sons.
