As for me, I go to Mass to worship God, in communion with His Church, as passed down from the Apostles and Church Fathers from ancient time. I go to participate in the Mass that Justin, Ignatius, Clement, Polycarp, Barnabas, Mathetes, Ireneaus, Origen, and the Apostles participated in while they were living. The Church of Augustine and Jerome, the Church of John Chrysostom. In the faith of our fathers.
If I omit any it is only through lack of space and lack of time.
I do not look on it as an obligation (though it is), but as a happy privilege, and a real gift.
True worship as passed down through Holy Tradition, as spoken of by the earliest writings of the Saints. The Eucharist. The very body and blood of our Savior, Jesus Christ, Son of God.
I am so glad that there are those like you that are called to the priesthood.
