A gangbuster parish priest draws in a few more, but not much more. The real draw for the daily attendee, that is, me, is being able to partake of the real Body, Blood, Soul and Divinity of Our Lord every single day of my life. Who WOULDN'T want that? I need food for my journey through this corporeal life and need food for my journey to Heaven. You know that we believe that the priest has the Jesus-given authority (Do this in memory of me.) to call down the Holy Spirit to change the bread and wine. It gives me peace, joy and hope.
I have an old friend in Texas who says that they have the same service of the changing of bread and wine in her Presbyterian Church. SHE also believes that the bread and wine are "transubstaniated."
Maybe it's different for Protestant churches.
Amen Brother!
