In Roman Catholic theology, during the sacrament of the Eucharist, transubstantiation means the change of the substance of wheat bread and grape wine into the substance of the body and blood of Jesus, while all that is accessible to the senses conveniently remains as before.

Limbo‏ [Noun.]

In Roman Catholic theology:

  1. from the 13th century to the 16th century, the place where innocent souls exist temporarily until they can enter heaven, notably those of the saints who died before the advent of Christ (limbus patruum) and those of unbaptized but innocent children (limbus infantum);
  2. from the 16th century onward, any in-between place, state or condition of neglect or oblivion which results in an unresolved status, delay or deadlock.
