Last night while Kristie and I were mailing some letters, we saw an advertisement announcing, “Music of the Sistine Chapel – Reflections on Palestrina, the Vatican and the Renaissance.”  So on the spur of the moment, we dropped in on the Chamber Choir of Idaho performance.  When they sang the lively “Tu es Petrus” at the end, it brought back a flood of memories of when my wife and I stood in St. Peter’s Basilica in Rome (take a virtual tour here).  At the base of the dome almost a football field up in the air, I remember looking up at the gold banner ring with the inscription of massive blue letters – “Tu es Petrus.”

Yet as a sinner saved by grace, I do not sing “Tu es Petrus” but “Agnus Dei” – “Lamb of God, who takes away the sins of the world.”

Christmas is the celebration of only One.  The Lamb of God.
