Biblical Inerrancy - mandatory to be Christian?

[Joel]

"I form the light, and create darkness: I make peace, and create evil: I the Lord do all these things." KJV

"I form light and create darkness, I make well-being and create calamity, I am the Lord, who does all these things." ESV

"formans lucem et creans tenebras faciens pacem et creans malum ego Dominus faciens omnia haec" Vulgate

(I can't read Greek or Hebrew)

I am well aware of the words. However, malum doesn't mean "evil" as we commonly use it. When you get fired from work, its malum. When you die in a video game, its malum. And yes, God gives us things that aren't pleasant. Intentionally.

That's different to creating evil, which you told me he didn't create because it would affect morality.
It doesn't matter if it means evil, or wrong doing (which a dictionary tells me it means - in latin)
God created it.

Unless we take into account Catfish's quote from earlier; in which case he may not have done.
