You literally can't be a faithful and go to mass because the mass is an abomination which enrages God. Because of the myth of transubstantiation, the mass is taught to be a sacrifice for the sins of the living and the dead, but according to scripture Christ on the cross put away the sins of His people once and for all. What's more, the bread is worshipped as a god, in violation of all biblical law and reason. Therefore the Romish mass is no Eucharist at all, but a grotesque idolatrous perversion of religion, as is rightly said by the Heidelberg Catechism: "the Mass teaches that the living and the dead do not have their sins forgiven through the suffering of Christ unless Christ is still offered for them daily by the priests. It also teaches that Christ is bodily present under the form of bread and wine where Christ is therefore to be worshiped. Thus the Mass is basically nothing but a denial of the one sacrifice and suffering of Jesus Christ and a condemnable idolatry."
