No, He didn't. The concept of purgatory is totally made up by the Catholic Church. To think that Christ forgives sins but man then has to somehow answer for them again is contrary to scripture and thus considered another gospel.
>>And moreover, the low-grade works are burned off purifying the soul. That's what the Scripture says.<<
No, that is NOT what scripture says. It says nothing about "purifying the soul" other then by the purifying shed blood of Christ. Even the verse you reference says nothing about "purifying the soul".
>>Read the Holy Bible once in a while<<
We do read scripture to "see if what you teach is true" and find it totally false. It's reading scripture that causes us to understand that what the Catholic Church teaches is in error and rife with paganism.
The Catholic Church has led people astray for centuries and will suffer the wrath of God. Those that stay in that "church" will be "partakers of her plagues".
It says nothing about "purifying the soul"
It says that inferior material like hay and stubble "burn, he shall suffer loss; but he himself shall be saved, yet so as by fire". The allegory is of a house (verse 9) that has good material and bad material in it and through fire only the good material remains, i.e. the house is purified.
