Could you show us from Scripture where Jesus required attendance at a Catholic mass every Sunday without fail and taught that it was a mortal sin to not do so?
For freedom Christ has set us free. We are not under the bondage of religious observances to try to keep God pleased with us or to try to appease Him.
Jesus didn’t save me just to demand I go to church every Sunday.
He saved me because He loves me and because of that, out of gratitude for what He’s done and what He’s given to me, I live for Him every moment of the day. Not just on Sunday’s.
It appears to me, that you enjoy freedom in Christ. 😱 Do you think that someone, somewhere, at sometime, is cringing at the thought? 🙀😱. Oh, the horror of horrors. 😆
