##"The prayer preceding Communion will change from "Lord, I am not worthy to receive you," to "Lord, I am not worthy that you should enter under my roof."##
What's to change. I have said,,"Lord, I am not worthy that you should enter under my roof." since I don't recall.
Memories of my childhood are coming back now.... I also remember "Lord I am not worthy to receive you under my roof, but only say the word and my soul will be healed." Did you have to say that 3 times? That part I don't remember.
At what point did they stop saying "and with your spirit?" I remember that too, but from a very long time ago.
