De sacrosancto eucharistiae sacramento theses theologicae

quality inherent in the words, but is the very use of the words, as it is divinely ordained toward that effect.

XXVII.
The primary EFFECTS of the Sacrament of the Eucharist are: an increase of habitual grace; certain actual aids by which the fervor of charity is recovered, and the taste of divine sweetness is reconciled, etc.; the remission of venial sins; preservation even from mortal sins; the union of the faithful through charity, both among themselves and with CHRIST the head; the right to eternal life and the attainment of it; and finally, the immortality of bodies after the resurrection.

XXVIII.
SECONDARILY, however, even the first grace, and thus the remission of mortal sins, is an effect of this Sacrament. Likewise, the remission of temporal punishment.

APPENDIX.
The Sectarii sectarians understand neither themselves nor us when they say the primary effect of this Sacrament is the remission of mortal sins, and in that matter they manifestly contradict themselves.

XXIX.
Furthermore, those alone who receive the Eucharist, insofar as it is a Sacrament, obtain its fruit; but if it is considered as a sacrifice, even those who do not receive it can be participants in its fruit.

APPENDIX.
Therefore, that consequence of the Sectarii sectarians is foolish: Baptism is of no benefit except to him to whom it is conferred. Therefore, neither is the Eucharist.

XXX.
And indeed, nothing but mortal sin hinders one from obtaining habitual grace or its increase from the opus operato the work performed, i.e., the inherent power of the sacrament itself of this Sacrament.
