Bad religion in the band's eyes, involves any assertion by any preacher to the contrary. Biblical religion however, provides the only reliable basis for morality. The ethic remains after the faith that bore it departs. But eventually a generation arises that no longer has the habit, and that is when the behavior changes radically . Gaffin's great-grandfather believed a Christian faith that promoted good religion which in turn promoted good morals for the general welfare of all society.
Bad religion produces bad morals.
Good religion produces good morals. The case of punk rock singer and evolutionary scientist Greg Gaffin and his great grandfather, a Bible scholar by the name of Zerr, is sad, but serves as a picture of what happens when Christian parents do not pass on the Christian legacy from one generation to the next. Ruth Graham Bell said that Christianity is but one generation away from extinction.
