Both James and 1 Peter say Christians ought to live as "slaves of God."
Actual slaves should obey, revere their masters, and endure cruelty with the patience of Jesus enduring suffering and death (2:18-20).
Women are to be subordinate (3:1-6).
In these things, the NT is entirely unanimous and consistent.
Likewise, NT writers, totally Jewish in this regard, with one voice condemn utterly the far less restrained sexuality of the Gentile societies by which Christians and Jews were surrounded.
In 1 Peter see 4:3-5.
Likewise 1 Peter and James share Paul's view that "The end of all things is at hand" (4:7a).
But 2 Peter 3:3-9 opens the prospect of a long delay of Jesus' return and the end of all things, "with the Lord one day is like a thousand years and a thousand years like one day" (3:8).
2 Peter 2:4-10, presents a rehearsal of various OT events (the Flood, the destruction of Sodom and Gomorrah) that takes them quite literally.
All of the NT writers are everywhere literalists, "fundamentalists", in their handling of Scripture and their express remarks about it.
And yet . . .
The comments in my NAB say modern scholars think James is by a later author attaching the prestige of James, brother of Jesus, to his own work, and that 2 Peter is also pseudonymous.
Likewise, Hebrews was for long falsely attributed to Paul.
On the whole, early Christianity seems to have been boiling with literary fraud and hoax, as well as vast amounts of plagiarism.
Only consider scholarly views about the Gospels.
And attestations of miracles, cures, and resurrections?
Always sincere delusions?
Never hoaxes, well meant or not?
