As near as I can figure out, technically “Christian” means only that people believe in Jesus Christ. Many make “Christian” out as meaning “good person,” which I find offensive, given that some of the best humans I know are not Christian while some of the most manipulative and cruel people in my acquaintance call themselves ordained ministers and/or fundamentalist Christians.
Most Christians like to claim that “Christian” means being kind, loving, forgiving. If they are confronted with not being kind, loving, and forgiving, they normally have reasons such as tough love, or being responsible for keeping their kids’ souls out of hell, or having to judge good and evil because Jesus commanded it. The list goes on and on and on. They seldom accept the complaints of their victims as being valid. As one of my Humanist friends said, “self righteousness is cruel.” I also know some truly good people who happen to be Christians.
