False prophets, false teachers, God haters, the antichrist? Who is John so concerned about, and who or what forces of evil in our midst should we be so worried about today?

[Editorial notes:

At minute 21:50, instead of "a divine force that let go of humanity,..." should have been "let go of divinity..."

At minute 23:26, instead of "empirical cross of Rome," should have been "imperial cross of Rome."

At minute 26:13, instead of "Irenaeus," should have been "Ignatius."]
