Dear Thomas:
Next  year I´ll be 50 years a priest.
You say:  "the priest is needed for the Eucharist, Confession and Anointing".
With all due respect and no wish to demean:
So the role of the priest is to be some sort of manager of a sacramental supermarket?
During all my years I have believed that it is much more than that and includes includes witness, prophecy.
... which has everything to do with "Do this in memory of Me".
The question: what exactly was it that he did that he wants us to remember, re-live & resurrect?
I believe the answer to that is in the doing and no so much in the saying (or even in the weekly
celebrating for an hour).
