The uniformity of expression across the first four authors affirms the literalness. Belief
in the real presence demands faith--the basis
of new life as called for by Christ throughout scripture. But faith in signs
conferring what they signify is the basis also for the
Incarnation--appearances belying true meaning. The true
significance of the real presence is sealed in John's gospel. Five times in
different expressions, Jesus confirmed the
reality of what he means.
Hence Catholic Christian belief in the real presence
of Jesus
Christ in the Eucharist rests upon the literal
meaning of the
words of the Last Supper as recorded by the
Evangelists and Paul.
