(a) Jude seems to be saying that his audience ought to recall what Peter (and Paul and his associates) had said to them regarding the rise of false prophets. Again, here it should be noticed that the verse is almost identical to 2 Pet 3:2, though Peter is speaking about what would come while Jude is saying that the prophecy was fulfilled.
(b) Again, as in v 3, v 17 seems to indicate that the age of the apostles was past.
(c) Finally, although Jude 17 and 2 Pet 3:2 are almost identical in wording, there are significant differences:
2 Peter 3:2—“you should remember the predictions of the holy prophets and the commandments of the Lord and Savior through your apostles” (RSV)
Jude 17—“Remember the predictions of the apostles of our Lord Jesus Christ” (RSV)
What shows very clearly the literary connection between these two texts is not only the general thought, but some key terms and expressions, for example:
mnhsqh'nai tw'n proeirhme'nwn rJhmavtwn (Peter);
mnhvsqhte tw'n rJhmavtwn tw'n proeirhmevnwn (Jude)
There are two major differences, however: (1) 2 Peter speaks of “your apostles” while Jude speaks of “the apostles”; (2) 2 Peter reminds his audience of what the prophets and apostles said while Jude merely mentions apostles. As we have argued in our discussion of 2 Peter, “your apostles” probably refers to Paul and his associates. Peter’s point was to show not only that Paul was a genuine spokesman for God, but also that his message was in line with the OT prophets. Jude, however, drops the mention of the prophets, and makes the apostles more absolute. If anything, this suggests that Jude was written later and depended on 2 Peter. (He might not have personalized the apostles because now such a group would include Peter and Peter was not, technically, one of “your apostles”). It is quite inexplicable for the author of 2 Peter, reading Jude, to add prophets and personalize the apostles, while it is perfectly clear why an author, after the age of the apostles had ended, spoke of them in more absolute terms and quietly dropped mention of prophets since that did not suit his purpose.37 In light of this parallel between the two epistles, it is rather surprising to read Bauckham’s comment that “there is no convincing case of allusion to a written Christian source [in Jude] … ”38
