"But now Christ has appeared as the high priest with regard to the good things of these new times. He passed through a sanctuary more noble and perfect, not made by hands, that is, not created. He did not take with Himself the blood of goats and bulls but His own Blood, when He entered once and for all into this sanctuary after obtaining definitive redemption."
--Hebrews, 9: 11-12
The Blood of Christ on the Shroud of Turin
"And the soldiers, platting a crown of thorns, put it upon His head; and they put on him a purple garment. And they came to Him and said: ‘Hail, King of the Jews!’ And they gave him blows." (Jn 19.2-3) Beneath the blows, the head oscillates pitifully from right to left, as is witnessed by the blood flows on the temples, in the form of an upside down "V": the blood took two directions alternatively, as the head leaned to one side or the other. Whereas on the brow a trickle "undulates serpent-like", as the Poor Clares of Chambéry would say: it follows the lines formed on the brow by the spasmodic puckering caused by the pain."
From His Holiness Pope Pius XII:
"Unlimited is the effectiveness of the God-Man's Blood - just as unlimited as the love that impelled him to pour it out for us, first at his circumcision eight days after birth, and more profusely later on in his agony in the garden, in his scourging and crowning with thorns, in his climb to Calvary and crucifixion, and finally from out of that great wide wound in his side which symbolizes the divine Blood cascading down into all the Church's sacraments.
"Such surpassing love suggests, nay demands, that everyone reborn in the torrents of that Blood adore it with grateful love. The Blood of the new and eternal covenant especially deserves this worship of latria when it is elevated during the sacrifice of the Mass. But such worship achieves its normal fulfillment in sacramental communion with the same Blood, indissolubly united with Christ's Eucharistic Body. In intimate association with the celebrant, the faithful can then truly make his sentiments at communion their own: 'I will take the chalice of salvation and call upon the name of the Lord. . . The Blood of our Lord Jesus Christ preserve my soul for everlasting life. Amen.'
"Thus as often as they come worthily to this holy table they will receive more abundant fruits of the redemption and resurrection and eternal life won for all men by the Blood Christ shed 'through the Holy Spirit.' Nourished by his Body and Blood, sharing the divine strength that has sustained countless martyrs, they will stand up to the slings and arrows of each day's fortunes - even if need be to martyrdom itself for the sake of Christian virtue and the kingdom of God. Theirs will be the experience of that burning love which made St. John Chrysostom cry out, 'Let us, then, come back from that table like lions breathing out fire, thus becoming terrifying to the Devil, and remaining mindful of our Head and of the love he has shown for us. . . This Blood, when worthily received, drives away demons and puts them at a distance from us, and even summons to us angels and the Lord of angels. . . This Blood, poured out in abundance, has washed the whole world clean. . . This is the price of the world; by it Christ purchased the Church… This thought will check in us unruly passions. How long, in truth, shall we be attached to present things? How long shall we remain asleep? How long shall we not take thought for our own salvation? Let us remember what privileges God has bestowed on us, let us give thanks, let us glorify him, not only by faith, but also by our very works.'
"You know well enough that your ransom was not paid in earthly currency, silver or gold; it was paid in the Precious Blood of Christ; no lamb was ever so pure, so spotless a victim. If only they would lend a more eager ear to the apostle of the Gentiles: 'A great price was paid to ransom you; glorify God by making your bodies the shrines of his presence.' Their upright lives would then be the shining example they ought to be; Christ's Church would far more effectively fulfill its mission to men. God wants all men to be saved, for he has willed that they should all be ransomed by the Blood of his only-begotten Son; he calls them all to be members of the one Mystical Body whose head is Christ.
"If only men would be more responsive to these promptings of his grace, how much the bonds of brotherly love among individuals and peoples and nations would be strengthened."
--From Pope Pius XII's encyclical Haurietis Aquas of May 15, 1956
