It doesn't say that in the scripture that I read...
1Co 3:15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
It says 'saved; yet so as by fire'...Not even saved by fire but saved as by fire...
The works get burned, not the man...No purgatory...
NIV has it as:
“If it is burned up, the builder will suffer loss but yet will be savedeven though only as one escaping through the flames.”
