“Easy. Either they are bored with mandatory Sunday Mass, OR they have given in to sexual temptation. Either way, automatic Mortal Sin. You go to Hell forever.”
This sounds like an opinion instead of a fact.
The comment about hell is not true for a believer.
It's TRUE for a Catholic believer!
They've been TAUGHT to somehow bypass THESE verses:
Matthew 12:31-32
And so I tell you, every kind of sin and slander can be forgiven, but blasphemy against the Spirit will not be forgiven.
Anyone who speaks a word against the Son of Man will be forgiven, but anyone who speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.
