The question to be asked in
seeking to grasp the literal
meaning of Matthew in
conveying what Christ had in his
mind in these words to Peter
is
what was understood by
Peter and the other apostles and
what was handed on (paradosis)
by the Apostolic Church
and the constant faith and
practice of the Church
regarding the meaning of
these words of Christ.
Some basic facts about the
author, Matthew, are in order to
aid the proper search for the
meaning of his gospel.
Matthew is the tax collector called by Christ in
9:9-13;
Matthew is one of the twelve Apostles, an eye witness;
Matthew's gospel is directed to a Jewish audience;
Matthew's gospel is a Gospel of the Church, the only
evangelist to use the word "church," and use
it
twice, 16:18
and 18:17.
