Is the Eucharistic Host bread? Or is It the Body of Christ? Can we call It 'Bread' after the Consecration? I remember long explanations given by myself to parishioners in Devon about how we should not talk about "taking the bread and wine". But there is a philological difficulty.
People are not always aware that the Latin (also the Greek) word means LOAF and only sometimes the substantia of BREAD.
There are two problems about translating PANIS simply as BREAD:
(1) One loses the meaning of phrases like UNUS PANIS, pointing as they do to a parallelism between the oneness of Christ's Eucharistic and Mystical Bodies. You will remember the very early Patristic topos of the symbolism expressed by the making of the one loaf from the innumerable grains of wheat.
(2) Referring to the consecrated element as "bread" suggests, misleadingly, that it is bread rather than Christ's Body (in Aristotelian-Thomistic terms, that the ousia or substantia of bread remains).
I don't think one can incorporate "loaf" into English renderings of liturgical texts, but I think it is a good idea for the thoughtful to be aware of this problem.
