Some years I ago, when ministering in rural England, I took over a public daily Mass after a priest had died. I made the appropriate enquiries of the bishop and got his permission to continue for the sake of the congregation attached to an old folks home. Permission was granted with the understanding that once I had finished my work in the area there could be no guarantee of continued provision. A year after I took over I sent a report to the ordinary of what was happening with the group. We had a Sunday Mass attendance of about 50, high days considerably more. I noted that over half the congregation were of school age or younger. The reply was, shall we say, just a bit frosty. The statistics were not what were expected.
My See and Pray Missal useful. I keep on running out of copies!
