Whether this sacrament is suitably called by various names?

❌ Objection 1 : It seems that this sacrament is not suitably called by various names. For names should correspond with things. But this sacrament is one, as stated above (Article [2]). Therefore, it ought not to be called by various names.

❌ Objection 2 : Further, a species is not properly denominated by what is common to the whole genus. But the Eucharist is a sacrament of the New Law; and it is common to all the sacraments for grace to be conferred by them, which the name "Eucharist" denotes, for it is the same thing as "good grace." Furthermore, all the sacraments bring us help on our journey through this present life, which is the notion conveyed by "Viaticum." Again something sacred is done in all the sacraments, which belongs to the notion of "Sacrifice"; and the faithful intercommunicate through all the sacraments, which this Greek word {Synaxis} and the Latin "Communio" express. Therefore, these names are not suitably adapted to this sacrament.

❌ Objection 3 : Further, a host [*From Latin "hostia," a victim] seems to be the same as a sacrifice. Therefore, as it is not properly called a sacrifice, so neither is it properly termed a "Host."
