UCANews has interesting information from Asia, but it’s often interesting to see what stories they pick up from around the world. Like this feature on five ways people have stemmed marriage break-ups in the US. Interesting that all five of these initiatives employ couples to assist the engaged, the married, and those in troubled marriages. No priests. No theologians. No TotB.
I’ve long thought we should offer a point of congratulations that marriages today last twice as long as they did a century or two ago. Would a troubled marriage of, say, the early 19th century, have more likely to ended in death or divorce? Likely the former.
Peer ministry works in a lot of places in churches. I’ve long thought that putting marriage prep in the hands of lay people and releasing priests for spiritual direction and liturgical presidency is a more effective use of resources, wisdom, and experience.
Catholic Sensibility 
My parents were immigrants to the USA. All the family marriages work – the couples are good friends to each other – and last. Children, nieces, nephews..Grandchildren too, and grand nephews and nieces. Here and in other countries. Making a marriage work is not that difficult. I agree, have married couples work with married couples and those who want to wed.
I don’t know…there are already many (too many, I’d argue) steps in marriage prep. They’d have to match the couples up well, otherwise it could backfire. For instance, a couple of cradle Catholics (or even where one converted) would send the wrong message to a mixed faith couple. You want to get the message out about the sacrament and how to live it, not one particular couple’s understanding of how that’s achieved, since there are many ways to do that, and not everyone’s relationship is the same. One couple may argue that “traditional” gender roles are the way to go, while another couple may not buy into it. See what I mean?
