For the Italian writer, see
Laurentius Abstemius. An abstemius (plural abstemii) is one who cannot take
wine without risk of vomiting. As, therefore, the consecration at
Mass must be effected in both species, of bread and wine, an abstemius is consequently irregular.St.
Alphonsus Liguori, following the opinion of
Suarez, teaches that such irregularity is de jure divino; and that, therefore, the
Pope cannot dispense from it. The term is also applied to one who has a strong distaste for wine, though able to take a small quantity. A distaste of this nature does not constitute irregularity, but a papal dispensation is required, in order to excuse from the use of wine at the purification of the chalice and the ablution of the priest's fingers at the end of Mass. In these cases the use of wine is an ecclesiastical law from whose observance the Church has power to dispense.
