Gregory the Great, on 1Pet 2:9

“But you are a chosen generation, a kingly priesthood, a holy nation, a purchased people: that you may declare his virtues, who hath called you out of darkness into his marvellous light:”

“Hence also it is said through Moses that whoever is burdened with a hump should by no means be advanced to the priesthood. And all of us who have been redeemed by the blood of Christ are made members of that same high priest. Whence also it is said to us through Peter: "But you are a chosen race, a royal priesthood." But he who bears a hump always gazes at the lowest things. Therefore he is driven from the priesthood, because whoever is intent only on earthly things is himself a witness to himself that he is not a member of the high priest.”
