Title I: On the Sacrosanct Sacrifice of the Mass

— Utility.

Choir of the new Jerusalem, applaud, And marvel what this victim is, Which Melchisedech the priest foresaw, Offering in praise, on the way, While mystically he met Abraham: Christ is figured, who is believed The living bread and fixed on the cross, Who rising again dies no more, Who, assumed, gives life to the mind; And into bread the wood is transformed, While the wood of the cross slays this one.

That excellent Prose of the Breviary of Bourges, which we borrow from the work of R. P. de la Taille, p. 74, wonderfully joins, in one context, the figure, the celebration in the Supper and on the Cross, and the consummation in the heavens of the sacrifice of infinite value by which Christ enriched the economy of the New Law, when through the Holy Spirit, that is, through the eternal power of divinity, he offered himself immaculate to God (Hebrews 9:14; cf. op. cit., p. 76).

But dogmatic theology vindicates to itself the solemn exposition of the mystery of our redemption, nor does it leave to moral theology except humble parts, almost canonical, which contain the disciplinary laws concerning the celebration of Mass and concerning its application. Yet daily use, and difficulties of conscience, which arise in great number, for example by occasion of stipends, sufficiently demonstrate the utility of accurate knowledge.
