What does "his strong faith in religion" bring to a marriage?

I stumbled across an article a couple of days back in the Huffington Post entitled If You Were More Religious, Would You Have Stayed Married?. In it, the author, when asked whether or not her marriage will last, said "yes", because "He's religious".

The article goes on to cite Brad Wilcox, director of the National Marriage Project at the University of Virginia:

Couples who attend religious services several times a month are 35% less likely to divorce

... A newer study found that shared religious attendance and especially shared prayers were associated with higher marital happiness," he added. The number was 73% for couples who both attend religious services and 63% with one partner regularly attending.

Yet, she seems to be missing out on the shared nature of belief. Later the article goes on to say that:

While my husband may find that connection in temple, I am more likely to find it in a spiritually-oriented yoga class I attend. One can access the divine in many places.

It seems fairly obvious that she and her husband disagree on a few fairly fundamental attributes of belief (although it's possible that her husband goes to a very liberal Jewish(?) temple). This lack of a shared system of fundamental beliefs seems to bode poorly for their marriage. According to a variety of research reported in the article Interfaith marriages are rising fast, but they're failing fast too, a significantly higher than average divorce rate would appear to be typical for a relationship such as their's.

I suspect that her self-described work as "a divorce coach" and that this is her husband's second marriage also boosts the likelihood of their marriage falling apart.
