Though that has nothing to do with my hypothesis, that real world considerations not to alienate a mostly christian audience was in play here.
What was most likely in play here was a realistic depiction of a wedding.
If the main purpose was tie into the religion of the largest group of Christian viewers, why was the bride not written to be Protestant, as opposed to Catholic?
What was shown on screen was a pretty average wedding ceremony. There was some prayer, the official mention faith, and the making of a pledge. Usually the fact that the ceremony is legal is briefly spoken of. There were candles and flowers. And the bride looked lovely.
Is there anybody still alive and capable of answering such a question?
I think Herb Solow is still alive, not sure though.
