What? The Evelelyn Lund Charitable Association? That isn’t even close to the LCMS!
The biggest differences that I’ve seen, having been to both, is that the Catholic mass seems to be all about what the priest can do for you and the sacrifice that he makes for you.
In the Lutheran church it is not about the priest or pastor, but about what the word does for you. For Lutherans, the words ‘this is my body, this is my blood’ are what bring the real presence into the Eucharist, and not the supposed changed character of the priest.
So,yes, as one poster noted the Catholic mass focuses on a sacrifice, the Lutherans do but not in the same way.
Other than that, many things are the same. The Kyrie, the confession, the Lords’ Prayer, the Apostles Creed, the sharing of the peace, all are pretty much the same.
