I think we really need to error on the side of compassion.
That pretty much sums up this thread.
Reading through it there is scriptural support for both arguments.
Yes, throwing and attending a shower for an unwed mother (regardless of the age) can be considered approval of and participation in a scandal. No doubt about that as the woman is pregnant as a result of scandalous behavior on her part (but let’s not forget the guy, here, either).
Mosher has repeated one can show their compassion for the young woman
privately by supporting her during her pregnancy, during the birth and after the birth. This can include providing her with medical care, clothing for her and the child, buying food, diapers, babysitting.
If I’m understanding Mosher correctly it is the public celebratory display of support which lends itself to participation in scandal, but I could be wrong.
However, there are plenty of passages in scripture which support public and private displays of compassion for sinners. Those of us who may not have the opportunity to be of assistance to the young woman
except through the invitation to this shower would not be wrong to attend or at least send a gift with a card.
I don’t know how Jesus will judge either side in the end, and the Church is not clear on matters such as these, so for me, I side with BLB and would rather err on the side of compassion than of strict interpretation of the law. Strict interpretation always makes me nervous because of the way Jesus chastized the Pharisees for such an attitude. Besides, I don’t understand a lot of the nuances of church teaching - tat catechism is great but teaches in a round about way leaving too much room for interpretation for my own comfort.
I believe, however, that if one behaved as Mosher suggests, do not attend the shower but make a point to reach out to this young woman in private ways, they would be acting as a good Catholic within the law and the spirit of that law.
The puritanical approach BLB mentions is a Catholic who not only does not attend the shower, but has no intention of supporting the woman at all - before, during or after the baby is born - and makes a point of trying to discourage others from supporting her as well…especially if they go around calling everyone a sinner for helping the girl. I don’t get the impression that was what Mosher was suggesting.
