VII. The power of the cross is universally attractive
O wondrous power of the Cross! O ineffable glory of the Passion, in which is contained the Lord's tribunal, the world's judgment, and the power of the Crucified! For you drew all things unto You, Lord and when You had stretched out Your hands all the day, long to an unbelieving people that gainsaid You, the whole world at last was brought to confess Your majesty. You drew all things unto You, Lord, when all the elements combined to pronounce judgment in execration of the Jews' crime, when the lights of heaven were darkened, and the day turned into night, and the earth also was shaken with unwonted shocks, and all creation refused to serve those wicked men.
You drew all things unto You, Lord, for the veil of the temple was rent, and the Holy of Holies existed no more for those unworthy high-priests: so that type was turned into Truth, prophecy into Revelation, law into Gospel. You drew all things unto You, Lord, so that what before was done in the one temple of the Jews in dark signs, was now to be celebrated everywhere by the piety of all the nations in full and open rite. For now there is a nobler rank of Levites, there are elders of greater dignity and priests of holier anointing: because Your cross is the fount of all blessings, the source of all graces, and through it the believers receive strength for weakness, glory for shame, life for death.
Now, too, the variety of fleshly sacrifices has ceased, and the one offering of Your Body and Blood fulfils all those different victims: for You are the true “Lamb of God, that takest away the sins of the world,” and in Yourself so accomplishest all mysteries, that as there is but one sacrifice instead of many victims, so there is but one kingdom instead of many nations.
