I expect that you might hope for one or both of the following to be included in the Homily:
1. A clear explanation of the Assumption. Many Catholics do not even know the basics about this Dogma.
2. A clear explanation about the significance of the Blessed Virgin Mary to our Catholic Faith, not only with regard to her Assumption, but in general. A combination of weak catechesis regarding Mary inside the Church, and a lingering – and sometimes still rabid -- antipathy among non-Catholics towards Mary and her crucial place in Christ's salvific work, requires fervent and focused preaching about Our Lady on a regular basis from the pulpit.
I will include both of these elements in my Homily, but I will also consider two reasons why many Catholics seem so unmoved by Mary's Assumption. Please check in again tomorrow and listen to the audio of my Homily. (A couple of advance hints: Most people today don’t get close to dead bodies a’mouldering anymore, and most people today consider themselves sufficiently free from the taint of any original or actual sin that might keep them from leaping directly into the bosom of Abraham.)
