Question to Roman Catholics regarding salvation

Can I why you think you are going to purgatory? Not to fight with you but I seriously have questions. Purgatory is not mentioned anywhere in the bible, nor anything that would describe a place like purgatory. So how can you know that purgatory is real? As far as you not being a practicing Catholic, to the best of my knowledge as a former Catholic in a family that is still Catholic, isn't your salvation based in part (notice I only say in part) on works? Works that include confession, communion and the like? Also, you say you follow the ten commandments but doesn't that include keeping holy the Lord's day by going to church? If you say you are not sure what would happen after purgatory, how can you be sure that you won't go to hell? As I said I am not trying to fight with you or anything of that nature; I am only wondering where you get your sense of assurance.

In case if you are confuse of have some question where did I get those things, or what chapter I got those information. I've give it to you next time. (Purgatory i mean on the first comment).

May I ask; are you a Jehovah's witness?

Yeah that about sums it up. But the problem with that is what happened to the salvation that was supposed to have been assured at baptism? (and then reconfirmed through the other sacraments)
