De sacrosancto eucharistiae sacramento theses theologicae

APPENDIX.
Opus operatum the work performed is a scandal to the Sectarii sectarians because they do not understand it at all.

XXXI.
Venial sins preceding communion will be an obstacle to their own remission in any effect that might otherwise flourish; but if committed during the communion itself, they will also hinder the taste of spiritual refreshment.

XXXII.
The Eucharist can be received in three ways: Sacramental-only, spiritual-only, and both Sacramentally and spiritually at the same time.

XXXIII.
Only humans who use their reason, or who, having previously used reason, desired to receive it, can be participants of the Eucharist properly and formally.

APPENDIX.
Hence, most of the trifles of the Sectarii sectarians are refuted.

XXXIV.
For you to receive the Eucharist worthily, a good conscience is required by divine law, namely that you judge without rashness that you are in the grace of God.

XXXV.
However, that judgment can and must rely on the certainty of infallible faith.

APPENDIX.
No one thinks themselves to be in grace less certainly and infallibly than the Sectarii sectarians, who require that certainty in the use of the Eucharist; indeed, they cannot even help but doubt that matter if they have reasoned consistently with their doctrine.

XXXVI.
That estimation of one's own grace (which is made more probable) ought to be supported not only by the consciousness of sorrow and internal penance, but also (unless sufficient necessity prevents it) by Sacramental confession.
