When raising my older daughter, I loved being able to tell her, without lying, that Santa Claus was real. He just wasn't like the Macy's version: he belongs to "the communion of saints," on "whose constant intercession we rely for help." I told her that St. Nicholas continues to do for children what he once did while on earth; only he does it with prayer, not a reindeer-drawn sleigh from the North Pole. I hope I thereby planted a conviction of the value of prayer.
Perhaps somebody out there can do the same for their children. At least, so I pray.
