I truly worship in the Mass, because the Mass is worship - a higher form of worship than that formerly available to me:
"Protestants, in their worship services, offer songs and praise and prayer to God; this is their highest form of worship. Since they don't have a priesthood, they have nothing else they can offer. Catholics on the other hand, offer the Sacrifice of the Mass to God. Our offering of sacrifice is made only to God and is our form of worship. This allows us to give lesser things such as songs and praise and prayer to those who can pray in our behalf before God: the saints and especially the Blessed Virgin Mary. When the Protestants see us offering what is their highest form of worship to someone other than God, it appears to them that we are worshiping someone other than God."
This quotation does not necessarily address a Catholic's nearness to God - there are countless Protestants who are nearer to God than I am - but it addresses, rather, the offering itself. And Protestants are unable to offer the true and proper sacrifice of the Mass, the Eucharist (Malachi 1.11). This reality left me questioning myself as an evangelical - If Christ is here, why am I not?
(And through the transition this quotation provides, I will next enter into the following reasons why I am Catholic: the Eucharist, which is the primary reason for my catholicity, and the communion of saints.)
