Was there a good point made in the sermon you heard for your Mass of obligation?
For my part, I had both EF and OF today, including a 1st Holy Communion. Nice.
I spoke about the liturgical year and its arc and our lives and their arcs. The Lord comes to us during both in various ways. Proper disposition for the ways that the Lord comes to us. To tie in the 1st Communion, which she received on the anniversary of her Baptism, I continued with the issue of disposition, but also said that disposition is a continuous focus throughout our lives, in view of the final way the Lord comes, to greet us in heaven, but that begins for us at a certain point in time in our lives. Everyone present should make sure their Communions are a pure and special as their First in view of the rest of our lives and the goal of heaven.
