Gregory of Nazianzus, on Ps 50:10

“To my hearing thou shalt give joy and gladness: and the bones that have been humbled shall rejoice.”

“In addition to what has already been said, those who cleanse the head, which is the seat of knowledge, would do well to hold fast to Christ as their head. It is from him that the entire body is joined together and reconciled. And to cast aside our sin which arises and to seek to surpass the better part. It is also good that they should cleanse the shoulder so that it will be able to bear the cross of Christ, which is not borne easily by everyone. It is also good to consecrate the hands and the feet—the hands so that they may be lifted up in every holy place and grasp the teachings of Christ lest the Lord be angered at any time and to believe the Word by living it as when it was given into the hand of the prophet; the feet so that they will not be quick to shed blood or rush into evil but that they may be ready to hurry to the gospel and to their high calling and to receive Christ, who washes and purifies them. If anyone is clean in his stomach, which is able to hold and digest the food of the Word, he should not make a god of nourishment and meat that perishes; rather he should especially reduce its size so that he may receive the Word of the Lord in its very midst and to grieve deeply over the failing of Israel. I also find the heart and the inward parts worthy of honor. David convinced me of this when he asked that a clean heart be created within him and a right spirit be consecrated in his innermost being—by this I think he clearly means his mind and its emotions or thoughts.”
