"Granting the existence of inscripturated revelation, there are three basic positions on the New Testament canon." What are they?

The three basic positions on NT canon in light of inscripturated revelation are two variations on an open canon and one view on a closed canon.  First, the view that the NT canon is an open human anthology which can be added to as new revelation is found.  Second, the view that NT canon can have have new word revelation given to individual people rather than the covenant people as a whole, maintains an open canon as well.  Finally, the view that the NT canon is closed is based upon the foundational  view of the apostles and prophets found in Ephesians 2: 19-20 and Revelation 21:14.  The closed view maintains the attributes of Scripture's complete sufficiency.
