Transignification

 Post Vatican II

A modern concept espoused by some Roman Catholic theologians as a rational explanation of the Real Presence of Christ at Mass. The theory is that He doesn't become substantially present, but that at the words of consecration the elements take on the real significance of Christ, so that He is sacramentally present.

This concept is based on the thought that there are two kinds of presence, local and personal. Jesus is personally, but not locally, present at the Mass. One can be locally present, as when riding on a bus, but ones thoughts can be far away, making him personally not present.

The theory hasn't been accepted by the Magisterium but is used by progressive priests who are embarrassed by the medieval tone of Transubstantiation.
