The answer
St. Ephrem the Syrian says (quoting Christ): “I call it My Body, and it is truly so. The smallest part of It is capable of sanctifying thousands of souls, sufficient to grant life to those who partake of it.”1527
The word ἀνάμνησις (anamnēsis) in Greek is not just a memorial or remembering something from the past that is absent from us now. Rather, it means repeating the event or the past action affecting the present in a very real sense. Anamnesis means recalling the crucified Christ who rose from the dead, or recalling His sacrifice not as a past event, but by offering a true and living sacrifice; an active remembrance.1528
