I never have thought ... nor taught ... nor have I EVER been in a church that taught that Judas was saved.
So let me understand what you are arguing.
1. You can loose eternal life (despite it being eternal) because there is an example in the scriptures ... Judas.
2. Judas was at one time saved because ... helping to baptize people implies he himself was baptized ...
3. Because he was baptized he had to be saved.
4. And then you move directly to ... he is in the pit of hell (the only thing we agree on) ...
So in fact, you are arguing that Judas WAS saved ?
2) No one will know if they are saved until the moment of death.
3) Eternal life comes after earthly death, not before.
Until you understand these three things there is no need for further discussion.
BTW stop trying to put words in my mouth.
