I told you I have Christ as my Savior and Lord and am indwelled by His Spirit. You didn’t answer my question. I will not ever be a member of the Catholic church - do you say I am bound for salvation or damnation?
Only you can answer the question about being bound for eternal life or eternal damnation.
If you die with a mortal sin on your soul — without having gone to the Sacrament of Penance/Confession and repented of it — then it is your choice.
FYI, once you have confessed your sins and been forgiven by GOD in the Sacrament of Penance, God forgets that sin.
Do you know the actual words of absolution?
