These are questions, which I think are very easily answered. Here’s why I don’t buy your argument. These influences that you have mentioned (the effects of the media? The advance of relativism? Easy, inexpensive, no-fault divorce? Less stability in employment? The growth of materialism, especially when compared to the time of the Great Depression? Greater mobility? )
These things have hit everyone in the USA, not just Catholics - right?
However, let’s look at the divorce rate in the USA and how it compares with the annulment rate in the RCC in the USA and see if there is any difference at all:
Divorces in the USA
1930: 195, 961
1979: 1,179,000
1998: 1,135,000
Annulments given out by the Catholic Church:
1930: 9
1989: 61, 416.
The divorces have increased by a factor of about 6
The annulments in the RCC have increased over the same period by a factor of 6824, or more than one thousand times as much as the divorces in the USA at large.
Now did you say that the increase in annulments is due to the surrounding culture??
If so, then why has the number of annulments in
the RCC gone up by more than one thousand times more than the number of
divorces in the surrounding culture?
Remember in 1930, you had the TLM exclusively in the Latin rite RCC.
