"Those who depart this world without sanctifying grace through ANY type of mortal sin can not be saved. That's Catholicism 101"

Not so . . . sin is the illusion of separateness​.  

"Who shall separate us from the love of Christ? Shall trouble or hardship or persecution or famine or nakedness or danger or sword? As it is written: “For your sake we face death all day long; we are considered as sheep to be slaughtered.” No, in all these things we are more than conquerors through him who loved us. For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord."

Romans 8:35-39
