(Part II)
The fact that the later phrase does not appear in the other gospels has been found to be quite suspicious - though there are many other incidents, but none as important, reported by one gospel and not the others and have gone unquestioned.  A stronger objection is that the word for "church" ("ecclesia" in Greek) occurs only twice in all four Gospels.  Another question is, based on the timing of this reported event, would Jesus of Nazareth really have been thinking, at such an early stage in His public ministry, of founding a church?
