MarkRome:
How did Vatican II and the spirit of Vatican II help support traditional family life? Why did we see an explosion in the number of Catholic marriage annulments right after Vatican II ?
Did we see it “right after” Vatican II? Let’s look at the numbers you posted:
The number of Catholic marriage annulments has increased dramatically after Vatican II, especially in the USA.
1929 - 10 marriage annulments per year.
1993 - more than 50,000 marriage annulments per year.
Recently it has been about 30,000 marriage annulments per year, but fewer Catholics are getting married. Since Vatican II, more Catholics are living together without getting married.
These are numbers for 1929 and 1993. Vatican II occurred in the 1960’s. These numbers do not demonstrate that “right after” Vatican II there was a massive increase because the only post-Vatican II number you give comes from about 30 years afterwards!
But I did attempt to do a little research on the numbers. According to this article:
https://www.catholicculture.org/culture/library/view.cfm?recnum=9607
"In 1970, the bishops of the United States obtained permission from the Holy See to modify canonical procedures in the adjudication of marriage cases. One judge, and not three, could render a decision, and cases could be heard in the diocese of the person seeking the annulment; in addition, appeal of a declaration of nullity to another court became discretionary rather than obligatory. The latter provision lapsed with the promulgation of the new Code of Canon Law in 1983, which expanded the grounds of invalid consent: “they are incapable of contracting marriage…who are not capable of assuming the essential obligations of matrimony due to causes of a psychic nature” (canon 1095).
Partly for these reasons, the number of annulments granted annually in the United States soared from 338 in 1968, to 28,918 in 1974, to a peak of 63,933 in 1991. By 2004 the number had fallen to 46,330, and it fell even further, to 35,009, in 2007–a remarkable decline of 24 percent in three years."
If this is accurate, the increase would be better applied to the adjustment in canonical procedures in the US, not Vatican II. This is further attested to when we consider the fact that, as mentioned in that article, the United States has 5.9% of the world’s Catholics but 60% of the world’s annulments (or at least it did in 2007, things may have changed).
To be fair, you did note “especially in the USA” but given that above figures it would appear that’s a bit of an understatement, and that if you were to remove the USA from the equation the rate would go down considerably.
