The new English version of the Roman Catholic mass may help convince the faithful that man does not live by bread alone, but for nuns who earn their living by making bread for Holy Communion the new rite brings serious problems.

Technology and liturgical in novation have teamed to force major changes in the produc tion of Communion wafers. As a result, some convents—like small farmers unable to auto mate—are being forced to abandon what for centuries has been a traditional means of support for contemplative orders.

The reason Is a recommen dation in the new Roman Catholic Missal that the host received by laymen during Holy Communion should “really appear to be food.” In the past, priests have adminis tered a thin wafer about the size of a quarter that quickly dissolves on the tongue with out chewing.

Last Supper Spirit Sought

The change reflects a grow ing concern in the last few years to recover the spirit of the Last Supper, which was a Jewish Passover meal observed by Jesus and his disciples, and to emphasize the communal, meal aspect of the communion rite.
