I have a sedevacantist, Traditional latin mass, non diocese affiliated church near me. Sister i talked to maintains all other religions are destined for hell, even Lutherans.
Im open to a conversion but idk. Imo Jesus doesnt need the middleman but ive been wrong before.
I was raised Catholic, converted as an adult to Lutheran (LCMS, which is a conservative synod - I say this because there are some newer "flavors" of "Lutheran" that should not be allowed to call themselves such). I beg to differ with the Sister.
Grace alone, faith alone, scripture alone.

I converted to Lutheran form Catholicism as well. I was tired of the fire and brimstone. Now I celebrate God's Love, Mercy, Grace and forgiveness. And now I don't have to do jumping jacks in church anymore.
