"You DARE to take the seat of Judgement from Christ Jesus?"
The great thing about the Bible is that in it God has clearly made known how He acts and what we can expect from Him on judgement day.
To merely repeat what God has already said is not an attempt to "take the seat of Judgement", rather, it is an affirmation of the truth of the Bible.
My statement was: "Catholics who think that if they don't pursue holiness and righteousness in this world they can deal with it in the next. In reality these people are more than likely lost - i.e. spiritually unconverted".
Now if you can't see that the above statement is Biblically sound, then you don't know your New Testament. It is clearly taught in the following passage...
"Do not be deceived: God is not mocked, for whatever one sows, that will he also reap. For the one who sows to his own flesh will from the flesh reap corruption, but the one who sows to the Spirit will from the Spirit reap eternal life." - Gal. 6:7&8
Catholics (or Protestants, Orthodox, or anyone else) who do not sow to the Spirit will surely reap hell. There will be no purgatory to save them.
