when was the canon closed - if it is closed

When do Baptists say the canon was established?

Is the canon closed? Does the establishment of the canon prevent God from communicating new information?

For example, Genesis instructs us to "multiply and fill the earth." Is there a mechanism by which God can inform us when the earth is filled . . . has enough people living on it?

If Jesus chose to return in some way not described in the Bible would Baptists accept him as the Christ or reject him as the Antichrist?

 

There is a fair chance the Pastoral Epistles were written after Revelation.



From http://www.ecclesia.org/truth/revelation.html

With the dating of Revelation, you establish the true historical prospective. If you date it early, you have its fulfillment in God's judgment on Israel. If you date it late, you have every man's idea. So dating plays a very important part in its interpretation.

There are differences of opinion as to when this book was written. These can be summed up as the "late date" and the "early date" theories. First, we'll cover the late date theory. Then we'll examine the facts which support the early date theory. . . .

Conclusion
If a person doesn't believe the first three verses of Revelation (i.e., the near expectation of the events), neither will he believe the rest of the book. For if a person is unwilling to accept the time constraints of the text, the rest of the document can mean anything that the reader desires.

If the Apostle John was banished to Patmos under the reign of Nero, as the internal evidence indicates, he wrote the book of Revelation about AD 68 or 69, which was after the death of that emperor; but the gospels and epistles some years later. One of the oddest facts about the New Testament is that what on any showing would appear to be the single most datable and climactic event of the period — the fall of Jerusalem in A.D. 70 — is never once mentioned as a passed fact.

The inscription to the book of Revelation, in the Syrian version, first published by Deuteronomy Dieu, in 1627, and, afterwards in the London Polyglot, is the following, "The Revelation which God made to John the evangelist, in the Island of Patmos, to which he was banished by Nero Caesar."

This places it before the year of our Lord 69AD.

Pseudepigraphic Letters: The three Pastoral Letters, along with three other Deutero-Pauline epistles (Col, Eph, 2 Thess), are attributed to the apostle Paul, but were almost certainly not written by Paul himself. Rather, they are probably pseudepigraphic (i.e., written in Paul's name by one or more of his followers after his death).

Date

It is "highly probable that 1 and 2 Timothy were known and used by Polycarp".[10] Irenaeus made extensive use of the two epistles to Timothy as the prime force of his anti-gnostic campaign, ca. 170 AD. Proposals by scholars for the date of their composition have ranged from the 1st century to well into the second.
The later dates are usually based on the hypothesis that the Pastorals are responding to specific 2nd-century developments (Marcionism, gnosticism). That Marcion (ca. 140) betrays knowledge of a collection of Paul's letters that lack the Pastoral Epistles is another piece of evidence for which any model must account.[11] (This is a separate question to Marcion's "canon", which included only edited versions of Luke and the Pauline epistles; according to Tertullian, Marcion "omitted" the Epistle to the Hebrews and the Pastoral Epistles.)
According to Raymond E. Brown (An Introduction to the New Testament, 1997), the majority of scholars who accept a post-Pauline date of composition for the Pastorals favour the period 80-100. Scholars supporting a date in this mid range can draw on the description in 2 Timothy 1:5 of Timothy's Christian mother and grandmother who passed on their faith, as alluding to the original audience being third generation Christians.
More recently, earlier dates have been argued by scholars who have identified targets of the epistles' criticism among those also known to Ignatius and Polycarp, who died in the early 2nd century.[citation needed]
Within the New Testament, these letters are arranged in order of size, though this does not represent a chronological order.

 

The process of establishing a canon is more about rejecting texts than including texts.
