“Do you think that knowingly missing Sunday Mass is not a mortal sin?”
Yes. It is a manmade event. Church wants donations on Sunday. Besides, Saturday is the Sabbath.
True. But there’s no substitute for being among a faith based group for an hour or so on Saturday or Sunday.
It may be for Jews, Seventh Day Adventists, or Seventh Day Baptists. But Jesus rose from the dead on Sunday.
Ah, but it’s in Scripture that gazing at a woman with lust in your heart equals adultery; therefore your hormone-driven synaptic firings & optic nerve receptors have just banished you to perdition!
Only half kidding...
