Whether there's any risk of pegnancy and disease or not, fornication is never "virtue." Chastity is the virtue: and chastity for the unmarried entails abstinence, not fornication whatever the circumstances.
Immoral, yes. I believe c-y-c may have been referring to a thread several years back, wherein a Catholic FReeper advanced the argument that 14 was the age of consent, and therefore a priest could not be tried for statutory rape or sexual abuse if the underage male was at least 14 years of age.
I'll leave it to others to decide if this person could be considered a "faithful Catholic".
Avoiding jail is a practical reason but not, NOT the chief, highest reason to not steal.
“Fornication is immoral:...” How would any Catholic know this? No fornication then no birth control or abortion or AIDS amongst the unmarried.
Is that the message? Or is just don't get caught?
Jesus gave the principle that to those given much, much would be demanded and hence could chastise Nicodemus for being a shepherd of Israel and yet not knowing what Jesus explained.
